5. hover barChart
This bar chart visualizes the frequency of letters in English text, with each letter’s bar height proportional to its occurrence rate. Hovering over a bar turns it brown, while non-hovered bars remain gray. Built with D3 v4 and SVG, the chart uses `d3.scaleBand` for the x-axis and `d3.scaleLinear` for the y-axis, with a `.tsv` data file providing letter-frequency pairs. Axis styling, tick marks, and labels are customized via CSS.
