This example demonstrates a simple D3.js v4 visualization that displays a static text message in the center of an SVG canvas. The code creates an SVG container with fixed dimensions and appends a text element that reads “Edit the code below to change me!” using the `d3.select` and `append` methods. The text is styled with a large monospace font and positioned at specific x and y coordinates. The visualization does not involve data loading or complex interactions, serving instead as a minimal template for users to modify. The rendering relies solely on SVG elements within an HTML document.
