This scatter plot shows the relationship between study hours and test scores using five custom data points. Each black circle represents one observation, plotted with hours on the x-axis and scores on the y-axis. The visualization uses d3’s `scaleLinear`, `extent`, `axisBottom`, and `axisLeft` within a reusable `scatterPlot` function to handle scaling, axes, and margins. The SVG rendering is configured with a fixed width of 800 and height of 500, and the chart displays labeled axes and axis tick marks.
