This fork of a scatter plot displays how a data point’s value changes over time, with a black line connecting sequential points overlaid on teal circles. It uses React to render an SVG, with axes and marks built from custom components. The code leverages d3.scaleLinear for scaling, d3.extent for domains, d3.format for tick labels, and d3.csv to load data from a remote testData.csv. The chart includes axis labels for “Time” and “Value,” and each circle shows a tooltip on hover.
