This interactive bubble chart visualizes the correlation between manufacturing cost, selling price, and profit percentage for various car makes, using data from a CSV file. The chart displays circles positioned by selling price on the x-axis and make cost on the y-axis, with bubble size scaled to profit percentage and color encoding brand identity. Built with D3 v7, it uses `d3.scaleLinear` for axes and bubble size, `d3.scaleOrdinal` for color mapping, and `d3.interpolateTurbo` for the color scheme. The visualization includes a legend and animated tooltips that appear on mouseover.
