d3js workshop - data binding
This example demonstrates data binding in D3.js, where an array of four names is joined to an empty selection of `<div>` elements using `d3.selectAll('div').data(...).enter()`. No visual output is rendered initially, as the `.append('div')` and `.text()` calls remain commented out, leaving the code as a starting point for a workshop exercise. The script loads D3 v3 from a CDN and shows how `.enter()` creates placeholder selections for each data item, with the actual text assignment to the bound data values commented out for participants to explore.
