This bar chart visualizes letter frequency data from a CSV file, plotting categorical values along the x-axis against their corresponding counts on the y-axis. Built with React 19 and D3 v7, the visualization uses `d3.scaleBand` and `d3.scaleLinear` for data mapping, with `d3.axisBottom` and `d3.axisLeft` generating labeled axes. An Unsplash background image renders behind the chart with partial opacity, while interactive bars respond to clicks, dimming non-selected elements and recoloring the active bar.
