This dashboard visualizes housing affordability and homelessness across U.S. states by merging two CSV datasets on state and year. It displays a grouped bar chart comparing the percentage of affordable housing against homeless population counts, with hover tooltips providing exact values. The visualization uses d3.scaleBand for the categorical axes, d3.scaleLinear for the value axis, and d3.scaleOrdinal for color encoding. Data is loaded asynchronously via d3.csv with Promise.all, and rendered as SVG elements with interactive mouseover events.
