This fork of D3 Starter demonstrates a minimal D3 version 7 setup, rendering a static grid of colored rectangles in an SVG canvas. The visualization shows a simple categorical heatmap-like pattern with varied blue, green, and yellow hues. The code imports the `select` function from D3 and uses it to update the page body text, while the SVG layout is hand-coded in HTML. No data loading or interactive behavior is included, focusing solely on the basic wiring of a D3 project.
