This visualization displays the average median home value by room count, arranged in descending order within each district. The bar chart uses color to encode the room count variable, creating a grouped comparison across districts. Built with the Vega-Lite API, it registers both Vega and Vega-Lite libraries, loads Boston housing data from a CSV via d3.csv, and renders interactive tooltips through the Vega Tooltip Handler. The chart’s appearance is customized using a dark color scheme, with axis ticks and guide labels styled for readability.
