Fork of D3 Starter
A blank SVG canvas forms the stage for a minimal drawing example. The code selects the `#svg` element and uses D3's data join to enter a range of ten values, appending a single line for each. The lines all start at the x-coordinate zero and have a black stroke, but no other attributes are set, so they appear as overlapping vertical segments. This demonstrates the foundational D3 pattern of binding data to SVG elements, though no visual layout or differentiation is applied yet.
