Fork of D3 v5 Zoomable Sunburst

This interactive sunburst chart visualizes the hierarchical structure of the Flare dataset, showing relative sizes of categories and subcategories as concentric arcs. Users click any segment to zoom into that branch, with smooth 750ms transitions animating the radial layout. Built with D3 v5, the visualization uses `d3.partition` for layout, `d3.arc` for path generation, and `d3.interpolateRainbow` for color coding. SVG rendering with `transition.attrTween` smoothly updates arc geometry and label positions during zoom interactions.

Fork of Force-Directed Graph V9

This force-directed graph visualizes application integration connections, with nodes representing software systems and links indicating data interfaces. Using D3 v7's `forceSimulation` API with `forceManyBody`, `forceLink`, `forceCenter`, and `forceCollide`, the layout balances node repulsion against link attraction. Draggable circles use the `drag` interaction, while grey lines and labels update positions dynamically. The graph is rendered as SVG, with node data from `applications.csv` and edge definitions from `interf.csv` representing real-world system dependencies.

SVG Fundamentals

This example demonstrates the basics of SVG rendering, showing three concentric circles that create a target-like visual using different colors and radii. The scene is constructed directly in an HTML page using the SVG element with a fixed canvas size of 960 by 480 pixels, while specific circle elements define their positions and fill colors. The visualization relies purely on static SVG markup without external libraries or JavaScript, illustrating fundamental vector graphics capabilities.
