This bar chart displays enrollment numbers for ten Indiana high schools, color-coded by their RECN status (Tier 1 or Tier 2). The visualization uses d3.csv to load the data, d3.scaleBand and d3.scaleLinear for positioning, and d3.scaleOrdinal for categorical coloring. Axes are rendered with d3.axisLeft and d3.axisBottom, while SVG rectangles represent each school’s enrollment. Data comes from the Indiana Department of Education’s 2019-20 school enrollment report.
