This example demonstrates the process of loading CSV data from a remote URL using JavaScript’s `fetch` API, with the fetched response logged to the console. The actual visualization, rendered as SVG, depicts a smiley face constructed with circles and an arc, built using the React framework and D3’s `arc` module for the mouth path. The code uses ReactDOM to render the SVG into the page, while the data source is a GitHub-hosted CSV file. The sample primarily focuses on the data-loading mechanism rather than the graphic’s interactivity.
