{"version":"1.0","type":"rich","title":"Line Chart","description":"This example positions simple geometric shapes to represent the physical locations of trees over time. An array of odd numbers indexes fifty points, while two parallel arrays drive the x and y positions. D3’s `interpolateRdYlGn` color scale maps data values to a green-to-red gradient, and the visualization uses the SVG `path` and `circle` marks. Global tree cover in the code is a parabola, not real geographic data. Referencing the D3 v7 library, the visualization demonstrates fundamental positioning and color-mapping channels for future GPS-coordinate data.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/87c1228181d1484896c96fde363fccb5?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
