{"version":"1.0","type":"rich","title":"E16 Loading Data with React & D3","description":"This example demonstrates how to load and summarize a CSV dataset using React state and D3 utilities. It fetches public transport performance data for New Zealand regions via the `csv` function from D3 v6, storing the parsed result in React’s `useState` hook. While loading, the view displays \"loading...\"; once the data arrives, it renders a text summary via `message.js`, showing the file size in kilobytes, row count, and column count. The visualization is purely textual, output in a large `<pre>` block with no graphical SVG elements.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f4d0931836324f089b4b036646cf09aa?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
