This example presents a simple Venn diagram with two overlapping circles rendered as inline SVG. The visualization uses plain HTML/CSS for styling, including a hover transition that changes the blue circle’s fill color via the `#blueCircle:hover` rule. Two white outlined circles highlight the intersection regions, while a title and border frame the 960×500 canvas. The source references the DataViz Catalogue for design inspiration, and the rendering relies entirely on SVG elements and CSS transitions rather than a JavaScript library.
