This interactive scatterplot shows the relationship between average teacher salary and high school graduation rates, with bubble size representing total student enrollment. School type is encoded through color, and hovering over a bubble reveals detailed information about the specific school. The visualization uses D3.js v7 with an SVG rendering approach, implementing scales via `d3.scaleLinear`, `d3.scaleSqrt`, and `d3.scaleOrdinal` for positioning, sizing, and coloring. Data is loaded from a local CSV file containing Massachusetts school information, with axes formatted using `d3.axisBottom`, `d3.axisLeft`, and `d3.format`.
