{"version":"1.0","type":"rich","title":"Line Chart","description":"This line chart compares population distribution across four regional parts for eight major countries, including China, India, and the United States. Data is loaded from a remote TSV file and parsed with `d3.tsv`. The visualization uses `d3.scaleLinear` for axes, `d3.scaleOrdinal` for color mapping, and `d3.group` to organize data by country. Each country’s line is rendered as an SVG path with interactive hover dots that trigger a tooltip, while grid lines and axis labels improve readability.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f4bc27c12c2845339f627d2edbcb79ef?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
