This scatter plot visualizes the relationship between students' math and reading scores, with each circle representing a student's performance on both subjects. The plot uses a procedural, reusable D3 module that defines a configurable `scatterPlot` function, which encodes data coordinates into circle positions using `scaleLinear` and `extent` for axis domains. The visualization renders as an SVG graphic, drawing steel-blue circles and adding left and bottom axes via `axisLeft` and `axisBottom`. It loads CSV data from a GitHub gist containing student test scores, and the code demonstrates a modular approach to building a scatter plot with D3 v6.
