This example shows two labeled line charts, “Home” and “Away,” tracking a numeric value across eight time steps, with hover interactions highlighting each line and its points. The visualization is built with React and D3 v5, using `d3.scaleLinear` for axes, `d3.line` for path generation, and SVG elements for rendering. Circles mark individual data points and show their values on hover, while lines increase in opacity and stroke width on mouseover. The chart includes bottom and left axes generated with `d3.axisBottom` and `d3.axisLeft`, and all transitions use D3’s `.transition()` and `.duration()` methods.
