Bar Chart in D3 v5
This bar chart displays the frequency of each letter in the English alphabet, with letters arranged along the x-axis and their proportional frequencies along the y-axis. It first parses a tab-separated values (TSV) file using `d3.tsv`, converting string frequencies to numbers. The visualization then applies `d3.scaleBand` for the categorical x-axis and `d3.scaleLinear` for the numeric y-axis, with axes generated via `d3.axisBottom` and `d3.axisLeft`. Rendered as SVG rectangles with a steelblue fill that turns brown on hover, the chart uses a conventional margin layout and highlights bars without tooltips or animation.
