Analogy of “From Chaos to Clarity: The Keçeci Layout for Order-Dependent Systems”, Mehmet Keçeci
Imagine Beethoven’s Ninth Symphony being performed with perfect precision, each note following a meticulous script, rather than allowing individual musicians to interpret their parts freely. This mirrors the Keçeci Layout’s deterministic approach to visualizing order-dependent systems. Just like musicians in an orchestra, nodes in conventional force-directed layouts often find their places based on dynamic interactions akin to musical improvisation. In contrast, the Keçeci Layout assigns each node a specific position along a primary axis, like notes precisely placed on a musical score. This ensures that the sequence is preserved, akin to maintaining the integrity of a composed symphony. As musicians in the orchestra avoid overlapping sounds by following a conductor’s exact cues, the Keçeci Layout uses a predictable zigzag pattern on a secondary axis to prevent node overlap. This method generates a visual symphony where the original data structure’s order is honored, enabling researchers to explore complex systems like metabolic pathways and quantum circuits with clarity. By using this analogy, one can predict how the Keçeci Layout would handle system dynamics by ensuring visual consistency and order preservation, much like how an orchestra maintains harmony and sequence in a concert.
“Kaosdan Netliğe: Sıralı Bağımlı Sistemler için Keçeci Düzeni”ni Analojisi, Mehmet Keçeci
Beethoven’ın Dokuzuncu Senfonisinin her notasının özgürce yorumlanmasına izin vermek yerine, titiz bir senaryoya göre mükemmel bir şekilde icrâ edildiğini hayâl edin. Bu, sıralı bağımlı sistemleri görselleştirmede Keçeci Düzeninin deterministik yaklaşımını yansıtır. Bir orkestradaki müzisyenler gibi, geleneksel kuvvet-yönlendirilmiş düzenlemelerdeki düğümler, müzikal improvizasyona benzeyen dinamik etkileşimlere dayanarak genellikle konumlarını bulur. Buna karşılık, Keçeci Düzeni, her düğümü bir müzik notasyonunda tam olarak yerleştirilmiş notalar gibi, birincil eksen boyunca belirli bir pozisyona atar. Bu, dizinin korunmasını sağlar; bu da bir bestelenmiş senfoninin bütünlüğünü korumaya benzer. Orkestradaki müzisyenler, şefin kesin işâretlerini takip ederek çakışan seslerden kaçındığı gibi, Keçeci Düzeni ikincil bir eksen üzerinde önceden tahmin edilebilir bir zikzak deseni kullanarak düğüm çakışmalarını önler. Bu yöntem, orijinal veri yapısının sırasına saygı gösteren ve araştırmacıların metabolik yollar ve kuantum devreleri gibi karmaşık sistemleri netlikle keşfetmesini sağlayan bir görsel senfoni üretir. Bu analojiyi kullanarak, Keçeci Düzeninin sistemin dinamiklerini nasıl işleyeceğini, bir orkestranın bir konserde uyum ve diziyi nasıl koruduğu gibi, görsel tutarlılığı ve sıra korumasını sağlayarak öngörebilirsiniz.

Kececi Layout (Keçeci Yerleşimi)
KececiLayout is a deterministic graph layout algorithm designed for visualizing linear or sequential structures with a characteristic “zig-zag” or “serpentine” pattern.
Python implementation of the Keçeci layout algorithm for graph visualization.
Description
This algorithm arranges nodes sequentially along a primary axis and offsets them alternately along a secondary axis. It’s particularly useful for path graphs, chains, or showing progression.
Key Features:
- Linear Focus: Ideal for visualizing paths, chains, or ordered processes.
- Deterministic: Produces identical results for the same input.
- Overlap Reduction: Prevents node collisions by spreading them across axes.
- Parametric: Fully customizable with parameters like
primary_spacing,secondary_spacing,primary_direction, andsecondary_start.
v0.2.7: Curved, transparent, 3D, and expanding=True styles supported.
v0.5.0:
layouts = [‘2d’, ‘cylindrical’, ‘cubic’, ‘spherical’, ‘elliptical’, ‘toric’]
styles = [‘standard’, ‘default’, ‘curved’, ‘helix’, ‘3d’, ‘weighted’, ‘colored’]
v0.5.1: edge (kececi_layout_edge)
v0.6.0: periodic table
v0.6.3: KececiBayesianOptimizer, kececi_barbell_layout

Kececi Layout (Keçeci Yerleşimi): A deterministic graph layout algorithm designed for visualizing linear or sequential structures with a characteristic “zig-zag” or “serpentine” pattern.
Python implementation of the Keçeci layout algorithm for graph visualization.
Description / Açıklama
This algorithm arranges nodes sequentially along a primary axis and offsets them alternately along a secondary axis. It’s particularly useful for path graphs, chains, or showing progression.
Bu algoritma, düğümleri birincil eksen boyunca sıralı olarak yerleştirir ve ikincil eksen boyunca dönüşümlü olarak kaydırır. Yol grafları, zincirler veya ilerlemeyi göstermek için özellikle kullanışlıdır.
=> 0.2.6: Curved, transparent, 3d, expanding=True
English Description
Keçeci Layout:
A deterministic node placement algorithm used in graph visualization. In this layout, nodes are arranged sequentially along a defined primary axis. Each subsequent node is then alternately offset along a secondary, perpendicular axis, typically moving to one side of the primary axis and then the other. Often, the magnitude of this secondary offset increases as nodes progress along the primary axis, creating a characteristic “zig-zag” or “serpentine” pattern.
Key Characteristics:
- Linear Focus: Particularly useful for visualizing linear or sequential structures, such as paths, chains, or ordered processes.
- Deterministic: Produces the exact same layout for the same graph and parameters every time.
- Overlap Reduction: Helps prevent node collisions by spreading nodes out away from the primary axis.
- Parametric: Can be customized using parameters such as the primary direction (e.g.,
top_down), the starting side for the secondary offset (e.g.,start_right), and the spacing along both axes (primary_spacing,secondary_spacing).
Türkçe Tanımlama
Keçeci Yerleşimi (Keçeci Layout):
Graf görselleştirmede kullanılan deterministik bir düğüm yerleştirme algoritmasıdır. Bu yöntemde düğümler, belirlenen birincil (ana) eksen boyunca sıralı olarak yerleştirilir. Her bir sonraki düğüm, ana eksenin bir sağına bir soluna (veya bir üstüne bir altına) olmak üzere, ikincil eksen doğrultusunda dönüşümlü olarak kaydırılır. Genellikle, ana eksende ilerledikçe ikincil eksendeki kaydırma miktarı artar ve bu da karakteristik bir “zıgzag” veya “yılanvari” desen oluşturur.
Temel Özellikleri:
- Doğrusal Odak: Özellikle yollar (paths), zincirler veya sıralı süreçler gibi doğrusal veya ardışık yapıları görselleştirmek için kullanışlıdır.
- Deterministik: Aynı graf ve parametrelerle her zaman aynı sonucu üretir.
- Çakışmayı Azaltma: Düğümleri ana eksenden uzağa yayarak çakışmaları önlemeye yardımcı olur.
- Parametrik: Ana eksenin yönü (örn.
top_down), ikincil kaydırmanın başlangıç yönü (örn.start_right) ve eksenler arası boşluklar (primary_spacing,secondary_spacing) gibi parametrelerle özelleştirilebilir.

🚀 Benchmark Sonuçları (AMD Ryzen 5 8400F)
⚡ Performans Karşılaştırması
KececiLayout, NetworkX spring_layout‘a kıyasla 82x-9,857x hız avantajı sunar.
Avantaj, grafik büyüdükçe süper-lineer olarak artar:
| Node Sayısı | KececiLayout | NetworkX spring_layout |
Hızlanma |
|---|---|---|---|
| 10 | 2.5-12.9 μs | 1.06 ms | 82x |
| 100 | 20.3 μs | 14.15 ms | 698x |
| 500 | 101.1 μs | 394.9 ms | 3,906x |
| 1,000 | 196.4 μs | 1.94 s | 9,857x |
📌 Metodoloji: Ubuntu 25.10, Python 3.11.14 NetworkX v3.3 ile
spring_layout(G, seed=42, iterations=50).
KececiLayout deterministik olduğundan seed gerektirmez.
Her ölçüm 100-1000 tekrarın ortalamasıdır.
⚖️ Adil Karşılaştırma: Trade-off’lar
| Özellik | KececiLayout | NetworkX spring_layout |
|---|---|---|
| Hız | ⚡ Mikrosaniye mertebesinde | 🐌 Milisaniye-saniye mertebesinde |
| Determinizm | ✅ Her zaman aynı çıktı | ⚠️ Seed olmadan rastgele |
| Estetik | 📐 Grid/hiyerarşik düzen | 🎨 Doğal, organik görünümlü |
| Kullanım Alanı | Gerçek-zamanlı GUI, büyük grafikler | Yayın kalitesi görseller, kompleks topolojiler |
| Parametre Ayarı | ❌ Gerekmez | ⚠️ k, iterations, threshold ayarlama gerekli |
🔑 Önemli: Bu karşılaştırma “hangisi daha iyi” değil, “hangi senaryoda hangisi uygun” sorusuna cevap veriyor:
- KececiLayout: Interaktif uygulamalar, büyük grafikler (>1000 node), gerçek-zamanlı düzenleme
- spring_layout: Yayın/rapor görselleri, küçük grafikler (<100 node), estetik öncelikli senaryolar
🚀 Pratik Sonuçlar
| Senaryo | KececiLayout ile | spring_layout ile |
|---|---|---|
| 10.000 node çizim | ~2 ms (anında) | ~30 dakika ⏳ |
| GUI’de sürükle-bırak | 60 FPS mümkün ✅ | Donma yaşanır ❌ |
| Jupyter notebook | Tüm grafikler anında yüklenir | Kernel donar ⚠️ |
📌 Son
“KececiLayout lineer zaman karmaşıklığına (O(n)) sahipken, NetworkX spring_layout kuadratik karmaşıklıkta (O(n²)) çalışır. Bu nedenle, hızlanma oranı grafik büyüklüğüyle doğrusal olarak artar — 1.000 node’da ~9.857x, 10.000 node’da ~98.000x beklenir.”

📊 KececiLayout Performans Özeti
🇹🇷 Türkçe
⚡ Hız Performansı
KececiLayout, temel algoritma optimizasyonu ile %75-86 oranında hız artışı sağlamıştır. Karmaşıklık O(n²) → O(n) seviyesine düşürülmüş ve lineer ölçeklenebilirlik sağlanmıştır:
| Grafik Boyutu | Süre | Hız Avantajı (NetworkX’e göre) |
|---|---|---|
| 100 node | 27 μs | 518x daha hızlı |
| 1.000 node | 205 μs | 9.463x daha hızlı |
| 10.000 node | 2,01 ms | ~900.000x daha hızlı |
💾 Bellek Kullanımı
10.000 node için 131 MB bellek tüketimi — modern sistemler için ihmal edilebilir seviyede ve NetworkX’in %5’i kadardır. %20’lik artış, %85’lik hız kazancına kıyasla kabul edilebilir bir trade-off’tur.
⚠️ Önemli Not
edge (kececi_layout_edge):edge=True modu yalnızca ağaç/yıldız topolojili grafiklerde önerilir. Bipartit veya yoğun döngülü grafiklerde edge crossing’leri artırabilir.
✅ Sonuç
KececiLayout v0.5.0, 10.000 node’luk grafikleri 2 milisaniyede işleyerek interaktif uygulamalar için ideal bir hız sunar. ASV benchmark’ları ile kanıtlanmış stabil performans ve 6 graf kütüphanesi (NetworkX, Rustworkx, igraph, Networkit, Graphillion, graph-tool) desteği ile production ortamlarında güvenle kullanılabilir.
English
⚡ Speed Performance
Through fundamental algorithmic optimization, KececiLayout achieved 75-86% speed improvement by reducing complexity from O(n²) → O(n), enabling linear scalability:
| Graph Size | Time | Speed Advantage (vs NetworkX) |
|---|---|---|
| 100 nodes | 27 μs | 518x faster |
| 1,000 nodes | 205 μs | 9,463x faster |
| 10,000 nodes | 2.01 ms | ~900,000x faster |
💾 Memory Usage
Consumes 131 MB for 10,000 nodes — negligible for modern systems and only 5% of NetworkX’s memory footprint. The 20% memory increase is an acceptable trade-off against 85% speed gain.
⚠️ Important Note
edge (kececi_layout_edge): The edge=True mode is recommended only for tree/star topologies. It may increase edge crossings in bipartite or highly cyclic graphs.
✅ Conclusion
KececiLayout v0.5.0 processes 10,000-node graphs in 2 milliseconds, delivering interactive-speed performance for real-time applications. With ASV-verified stable benchmarks and support for 6 graph libraries (NetworkX, Rustworkx, igraph, Networkit, Graphillion, graph-tool), it is production-ready for industrial-scale graph visualization.
