{"version":"1.0","type":"rich","title":"line chart Saranya","description":"This example shows how forest area in South American countries has changed annually from 1990 to 2015, with each country’s net forest conversion trend drawn as a separate blue line. The chart uses d3.csv to load the data, d3.timeParse and d3.scaleTime for the year axis, and d3.nest to group values by country. A d3.line generator creates the SVG paths, while d3.scaleOrdinal assigns distinct colors to each country. Interactive tooltips appear on hover, and the chart includes a title and legend built with SVG text elements.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1d6ca2c7ea67415ca3ea63d57f7c1fb0?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
