{"version":"1.0","type":"rich","title":"Untitled","description":"This example presents a bar chart visualization of income data over time, displaying values for multiple countries as a chronological series. The code loads a CSV dataset from an external GitHub URL using D3’s `d3.csv` method, then processes the data with `d3.rollup` to aggregate values by date and country. The chart sorts the resulting date-value pairs in ascending order using `d3.ascending`. The visualization is built with D3 v5 and appears to be a static or interactive racing bar chart, though the rendering logic is not fully implemented in the provided files. The HTML includes CDN links to both D3 v5 and d3-array v2, and the CSS uses a dark blue background with Ubuntu font styling.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/19a39c1b8d48417f85da26de89464c9c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
