{"version":"1.0","type":"rich","title":"Activity-7.1_Q2","description":"A mobile phone price area chart visualizes monthly cost trends over time. The D3 v5 code (using `scaleTime`, `scaleLinear`, `line`, `area`, and `curveBasis`) renders smooth lines and gray shaded regions beneath them, with labeled axes for month and cost. Data is loaded from a CSV file via `csv` and parsed with `d3.timeParse`. Axes include gridlines via `tickSize`, and the SVG output uses styled paths with bold tick labels.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4d995a64744e4e8a9bb3c080d61c5615?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
