This example demonstrates wind barbs drawn with D3 v7, displaying six distinct SVG icons that encode wind speed and direction through barbs, short bars, and triangles. The visualization uses a custom WindArrow class that converts speed and direction values into paths, with the barbs rendered inside separate SVG containers within a Bootstrap layout. The code also includes a zero-wind case that draws circles using d3.arc, and the overall example invites creative modifications for themed variations.
