Loading and Parsing Data

This example shows how to load and parse data from an external CSV file into a web page. It fetches a remote CSV containing CSS named colors using the Fetch API, then logs the raw text to the browser console. The code uses the native `fetch` function with an async/await pattern to request the file from a GitHub Gist URL. This bare-bones HTML page demonstrates the foundational step of data retrieval before any visualization is created, relying solely on vanilla JavaScript without external libraries or frameworks.

smiley face

A yellow smiley face rendered as SVG via React components shows geometric shapes: a circle background, two eyes, and an arc-based mouth. Each facial feature is a separate React component—BackgroundCircle, Eyes, and Mouth—composed within a FaceContainer that applies a centered translate transform. The Mouth uses d3.arc with specified inner and outer radii and start/end angles to draw the smile. Hardcoded dimensions for the face, eyes, and stroke width define the static visualization.
