This example presents two interactive scatter plots comparing student performance metrics: hours studied versus exam score, and sleep hours versus exam score. Using D3 v7, the visualization displays data points as circles with tooltips showing details on hover. The code implements a reusable `ScatterPlot` function that builds SVG charts with linear scales, axes, and axis labels, while reading data from `studentscores.csv`. Dark tooltips with rounded corners provide additional context for each data point.
