This interactive bar chart shows monthly sales figures, with each bar representing a month’s sales value from the `Sales.csv` dataset. The chart supports clicking on a bar to highlight it, visually distinguishing the selected month by changing its fill to white with a black stroke. The visualization is built with React and D3 v7, using `d3.csv` to parse the data, `d3.scaleBand` and `d3.scaleLinear` for scales, and `d3.axisBottom` and `d3.axisLeft` for axes, all rendered as SVG within a responsive container.
