This visualization displays a bar chart of average musical instrument prices by category, sorted from highest to lowest. The bars use a sequential color scale that maps price values to a cool-toned interpolator. Built with D3.js version 7.8.5, it loads CSV data from a GitHub gist, aggregates the dataset with `d3.group` and `d3.mean`, and renders SVG elements with smooth mouseover transitions that highlight bars and show tooltips with exact average prices.
