A bubble chart plots student algebra scores against literature scores, with circle sizes encoding daily study hours. Each circle represents a student, and hovering reveals a tooltip with the student's name and exact values. The visualization uses D3 v7 with SVG rendering, employing `d3.scaleLinear` for the axes and `d3.scaleSqrt` for bubble radius. Data comes from a CSV file loaded via `d3.csv`, with interactive tooltips implemented through mouseover and mouseout event handlers.
