This bar chart displays the count of awards for categories A through G, with a title reading "Data Visualization" and labeled axes for Awards and Count. Built with React and D3 v7, it uses `scaleBand` and `scaleLinear` to position bars, `axisBottom` and `axisLeft` for gridlines and ticks, and loads data from a CSV. Clicking a bar toggles its selection, highlighting it in a darker blue while dimming others. The chart is responsive, using a ResizeObserver hook to update dimensions.
