{"version":"1.0","type":"rich","title":"Zoomable Bar char","description":"This visualization displays the long-term trend of global CO₂ concentration in parts per million, plotted as a zoomable bar chart that highlights historical fluctuations from over 800,000 years ago to the near present. The chart uses the D3 library (v6) to load CSV data, parse it with `d3.csvParse`, and filter for the World entity before mapping the year and concentration values. Bars are rendered in an SVG via `d3.create`, with zooming enabled to allow users to inspect dense early periods or recent dramatic increases. The data comes from the provided `co2-concentration-long-term.csv` file, processed entirely client-side.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a360a257521b4846a796f6085bf4abbf?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
