This example displays a closed polygonal line connecting eight points in a two-dimensional coordinate space, forming a shape reminiscent of a star or a triangle-pentagon hybrid. The visualization uses the D3.js v4 library’s `d3.line()` path generator to convert the array of x-y coordinates into an SVG `path` element, which is then rendered with a blue stroke and no fill. The code appends the SVG container to the document body via `d3.select()`, hardcoding the 1000x1000 pixel canvas and the data points. The geometric pattern is drawn as a single continuous path, illustrating how D3’s line interpolation handles multiple segments within one dataset.
