Multiple Line Chart with ToolTipV2
✓ Published0🌍 Public
This example shows how state populations in California, Michigan, and Texas changed from 1910 to 2010 using a multiple line chart with color-coded lines and a legend. The visualization also provides an interactive tooltip that appears on mouse movement, displaying the exact year and population value for each state. It uses D3 v4 with SVG rendering in a React framework, leveraging `d3.line`, `d3.scaleLinear`, and `d3.axisBottom`/`d3.axisLeft` to construct the chart. An invisible overlay rect captures mouse events, while a separate tooltip div and vertical guide line highlight data points.
