Combined Chart
✓ Published0🌍 Public
This combined chart displays daily steps, calories burned, and heart rate data for a fitness tracking scenario. Bars show raw step counts, while a red line represents calories burned and a green line shows heart rate, using separate scaling factors to align these different magnitudes on a shared axis. The visualization is built with the D3.js v7 library using a CSV dataset loaded from a GitHub gist. It combines an SVG bar chart with two line charts, utilizing D3’s scaleBand, scaleLinear, axis, and line generators to render the layered graphic.
