This interactive bar chart displays the maximum salary for each of the first 20 employee locations from a CSV file. The visualization uses React to manage state and D3.js v5 for rendering, with `d3.csv` fetching the remote data and `d3.scaleBand`/`d3.scaleLinear` mapping categorical locations and salary values to SVG rectangles. Axes and gridlines are drawn manually via D3’s scale objects, and the chart updates asynchronously after data loading.
