Making a Bar Chart
This horizontal bar chart displays crop areas for six crop types, with each bar’s length proportional to its area value. The visualization uses D3 v5’s `csv` loader to read data, `scaleLinear` and `scaleBand` for positioning, and custom `axisBottom` and `axisLeft` axes. The code removes default axis domains, formats tick labels with `format('.3s')`, and colors bars steelblue via CSS.
