{"version":"1.0","type":"rich","title":"ques2-task9","description":"This visualization shows the number of iPhone users from 2007 to 2017, combining a black line chart with a filled area beneath it to emphasize the upward trend. The chart uses D3 v5 APIs including `d3.csv` to load data from a remote GitHub gist, `d3.scaleLinear` for both axes, and `d3.line` and `d3.area` with `curveBasis` to generate the line and area paths. Styling is defined in a separate CSS file, with green tick labels, orange gridlines, and a purple title.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1109a0592dbe42508a6d6d0e9d89844c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
