{"version":"1.0","type":"rich","title":"Assignment 2 Question 2(a)","description":"This area chart displays mobile phone costs over time, with monthly data points connected by a smooth curve and the region beneath the curve filled in gray. The visualization uses D3 v5’s `scaleTime` and `scaleLinear` for axes, `line` and `area` generators with `curveBasis` for smoothing, and parses date strings from a remote CSV file using `d3.timeParse`. Axis labels and ticks are styled via SVG elements and CSS.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ae2dbc9a780f4d65981730ae2c562023?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
