Bar chart
This bar chart displays categorical data from a CSV file, mapping values to vertical bars within an SVG container. The example uses D3 v6’s `select` and `csv` methods to load and parse the external dataset, while the SVG’s width and height attributes are read to define the chart’s dimensions. Currently, the code logs the parsed data to the browser’s developer console but does not render any bars, serving as a minimal starting point for a React-based visualization.
