This scatter plot visualizes a student dataset with marks, study time, and course count. Built with D3 v6, it uses a reusable chart pattern with scaleLinear, axisBottom, axisLeft, and SVG circles. The plot cycles its x-axis variable through three columns every five seconds, animating the data transition via setInterval. Data comes from a CSV loaded with d3.csv, and the chart updates in place when the x-value changes.
