This bar chart demonstrates how to build a basic bar chart with D3.js. It renders a static SVG and uses D3’s `select` and `csv` functions, though the data loading and bar drawing logic are not shown in the visible code. The SVG dimensions are read dynamically from the element’s attributes, and the chart is styled with a simple CSS reset that removes page margins and hides overflow. The example relies on D3 v5 and is authored by AmitaAnton.
