This example shows a simple bar chart where each rectangle is rendered in steelblue, with a single text label displayed beneath the visualization. The chart uses D3.js to bind data from a CSV file to SVG elements, mapping values to rectangle heights. The code relies on D3’s selection and data-join methods to append the `rect` and `text` elements, while the page layout is controlled by CSS, setting margins to zero and hiding overflow for a full-window display.
