{"version":"1.0","type":"rich","title":"2.8 - Activity: Your first visualization!","description":"Five horizontal bars display the heights of five skyscrapers, loaded from a local JSON file and rendered as SVG rectangles. The visualization uses D3.js v5 with `d3.json` to fetch and parse the data, converting each height string to a number. Bars are appended to an SVG canvas with fixed dimensions, using `selectAll` and `enter` for data binding. Each rectangle’s height is mapped directly to the data value, with grey fills and uniform positioning along the x-axis.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/164bc6c258c14e6888f4514a7b7f6d15?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
