This example demonstrates a React and D3.js starter template with a configurable SVG container that follows the margin convention. The React component `VizContainer` renders an SVG with optional margin visualization, controlled via the `showMargins` prop. The app fetches profile statistics from the Lens API using the `urql` GraphQL client, querying data such as followers, following, posts, mirrors, and comments for a specified handle. The fetched data is logged to the console, while the visualization area remains empty.
