Learn D3.js
A simple bar chart built with D3.js v5 demonstrates how to create an SVG visualization from a static array of data. The page displays a single titled bar chart rendered inside an SVG element, using D3’s selection and scale methods to map data values to pixel heights. The code also includes a separate Hello World message written to a DOM element, but the chart itself does not reference external data files or interactive features. The example serves as a minimal introduction to D3’s core SVG rendering workflow.
