This scatter plot visualizes the relationship between students' subject scores and team scores. Each data point is rendered as a circle, with blue circles animating in from a zero radius via a D3 transition, and hovering turns a point red while displaying a tooltip with both scores. The visualization uses D3 v7 scales and axes (d3.scaleLinear, d3.axisBottom, d3.axisLeft) to map the tab-separated dataset fetched with d3.text. SVG elements provide the interactive chart, including animated point entry and mouse-based interactivity.
