{"version":"1.0","type":"rich","title":"Hello VizHub","description":"This example demonstrates a minimal D3.js workflow in VizHub, loading a small CSV dataset that maps student names to exam grades. It uses `d3.csv` to fetch the data and logs the parsed array to the browser console within a `render` function, while the page itself remains visually empty aside from an empty `#chart` container. The code styles the body with an Ubuntu font and large text, but performs no chart rendering or DOM manipulation beyond data loading.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
