This example demonstrates a minimal blank canvas that immediately clears and refreshes its visual state when the underlying code changes, leveraging hot reloading to visualize the update cycle. It uses a plain SVG element with no data source or marks, but the rendering approach relies on the code’s lifecycle hooks to wipe prior content. The implementation uses `d3.select` and `d3.selectAll` to manage elements, with the page’s hot-reload mechanism triggering a full redraw. The example serves primarily as a development template for testing how alterations propagate to the live visualization.
