This bar chart visualizes Indian startup data from a CSV file, mapping company names along the x-axis and city indices along the y-axis. Animated SVG rectangles transition when sorting buttons are clicked, reordering bars by ascending or descending city values while blue circles mark the exact data points. Built with d3.v5, the visualization uses scaleBand, scaleLinear, axisBottom, axisLeft, and transition methods, with tooltips displaying company and city information on mouseover.
