Fork of Melting Data for Multiple Lines

This visualization shows population trends over time for multiple world regions, with each region represented as a colored line. It displays data from 1950 to 2100, combining UN population estimates with medium variant projections. The chart orders lines by their final population values and uses a legend to identify regions. The code employs d3.nest for data grouping, d3.line with curveBasis for smooth paths, and d3.scaleTime for the time axis. The underlying data is melted from wide to long format, with yearly values converted to date objects.

A line chart displays 21 randomly generated data points as a smoothed orange curve, with dots marking each value along the x-axis. The visualization uses D3’s `d3.line` generator with `curveMonotoneX` for interpolation, while `d3.scaleLinear` maps the data index and random y-values to pixel coordinates. SVG circles are appended for each point, and mouseover events log the bound datum to the console, though no tooltip or interactive highlight is implemented. The chart includes x and y axes via `d3.axisBottom` and `d3.axisLeft`.

A force-directed network graph maps relationships between board games, with blue solid edges for 0-value links and dashed lines for 1-value links. Node size and color intensity scale with degree, while labels identify each game. Built with React and D3 v5, the visualization uses `d3.forceSimulation` with link, center, charge, x, and y forces. Interactive features include dragging via `d3.drag` and double-clicking to fix nodes, which adds an orange stroke.

Graph

This example visualizes a network of board game relationships as an interactive force-directed graph. Nodes represent distinct games and are rendered as small circles, while curved paths between them show connections weighted by a numeric value. The visualization uses `d3.forceSimulation` with link, charge, centering, and X/Y forces to position nodes, and supports dragging with `d3.drag` to manually reposition elements. The graph reads its source and target pairs from a imported CSV file, with SVG elements styled via external CSS.

Force Layout Example 1

Two circles connected by a single line demonstrate a basic force-directed graph layout. The D3.js v3 code uses `d3.layout.force()` to position the nodes and link, with the simulation running until it reaches equilibrium. The SVG rendering applies CSS classes for node and link styling, and the final coordinates are applied to the circle and line elements after the force calculation completes.
