Hello HTML
This example demonstrates VizHub’s ability to combine static HTML structure with dynamic D3.js operations. It renders a single yellow circle with a black stroke on a 960 by 500 SVG canvas, while a D3 `select` API call updates a div’s text content to "Hello VizHub!" using a local ES6 module. The page loads D3 from UNPKG and imports a custom `message` function from `./myMessage`. The visualization relies entirely on inline SVG markup and CSS styling, with no external data source.
