{"version":"1.0","type":"rich","title":"Line Chart with Multiple Lines","description":"This line chart displays population estimates for four animal groups—birds, cats, dogs, and fish—across multiple countries, using a multi-line layout to compare trends by country. The visualization renders as an SVG and uses D3 v5 APIs including `d3.csv`, `scaleLinear`, `scaleOrdinal`, `axisBottom`, `axisLeft`, and `nest` to structure the data. Color encodes animal type via `schemeCategory10`, while the axes show country and population values. The chart is built from `data.csv` and styled with external CSS.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/fbc5fd49f4b84b2b905a0f822dc651f5?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
