Fork of Responsive Bar Chart
✓ Published0🌍 Public
This example presents a racing bar chart that animates changes in foreign aid allocations over time, using a responsive design that adapts to screen size. The visualization relies on D3 v7 to bind data, update bar dimensions, and orchestrate transitions between states. It uses `d3.interval` to cycle through dataset years, while `transition` and `duration` handle the smooth movement of bars as values shift. The bars are scaled using `d3.scaleLinear` and `d3.scaleBand`, with axis updates driven by `d3.axisBottom` and `d3.axisLeft`. Data originates from an external CSV loaded via `d3.csv`, and the layout recalculates on window resize via `d3.select` event handlers.
