This fork of Hello VizHub demonstrates a simple data-binding example using D3 v7, where an array of three letters is mapped to span elements in the DOM. The code uses `d3.selectAll` with `.data()` and `.enter().append()` to create the spans, then `text()` to display each value. It also loads D3 twice via CDN scripts and includes commented imports for local ES6 modules, showcasing VizHub’s module loading capabilities alongside basic selection and binding patterns.
