{"version":"1.0","type":"rich","title":"Assignment 2","description":"This line chart displays iOS usage over time, plotting user counts against yearly dates. The visualization uses D3 v6 with an area path rendered in purple, employing scales from `d3.scaleTime` and `d3.scaleLinear` to map data points. Axes are generated using `d3.axisBottom` and `d3.axisLeft`, with tick formatting converting values to billions. Data comes from a CSV file, parsed with `d3.csv` and `d3.timeParse`, sourced from the Data Canvas Sense Your City initiative. The SVG-based chart includes labeled axes and a title, with styling defined in external CSS.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d8d59f7326124b56ab335e3ae4ce1d7a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
