fresh block
This example is a simple starter template that displays the text "Edit the code below to change me!" in a monospace font on an SVG canvas. It uses D3 v4 to select the body, append an SVG element with fixed width and height, and add a text element with specified positioning and styling. The visualization is rendered entirely with the d3.select and append API, with no external data source or interactive behavior. It serves as a minimal, blank-slate block for users to modify and build upon.
