This example displays a blank SVG canvas with no visible chart, as the code only sets up the basic structure for a bar chart. The React-based visualization uses D3 v6, importing the `select` function to access the SVG element and reading its width and height attributes. The page loads data from `data.csv` and applies monospace styling, but the bar-rendering logic is not implemented. The code represents the minimal starting point for a D3 bar chart, with the data source and rendering approach yet to be developed.
