This scatter plot visualizes the relationship between students’ study hours and their exam scores. The chart uses D3.js v7 to render SVG circles, with a linear scale mapping study hours on the x-axis and exam scores on the y-axis. The data is loaded from a CSV file via `d3.csv`. Axes are added using `d3.axisBottom` and `d3.axisLeft`, with labels for both variables. The code defines a reusable `createScatterPlot` function that takes data and a container ID, setting fixed margins and a 600x400 pixel drawing area.
