This example renders a bar chart of garage capacities by province inside an SVG element. It loads JSON data from a GitHub gist using D3’s `json` function, then maps capacity values to bar widths with `scaleLinear` and province names to vertical positions via `scaleBand`. The code demonstrates a minimal HTML/CSS/JavaScript setup with D3 v6, though the y-axis scale is configured but not fully applied, leaving bars unpositioned vertically.
