{"version":"1.0","type":"rich","title":"Fork of Activity 7_2","description":"This fork of Activity 7_2 displays an area chart of smart mobile users from 2007 to 2024, using a smooth curved line and filled area to show growth over time. The visualization is built with D3 v5, importing `select`, `csv`, `scaleLinear`, `axisLeft`, `axisBottom`, `line`, `area`, and `curveBasis` to create the SVG-based chart. Data is loaded asynchronously from a remote CSV file, with the x-axis representing years and the y-axis showing user counts formatted in compact notation. The chart includes labeled axes and uses margin-based layout with grid lines provided by tick sizes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a83cbaddf16d42aaad8416ce3295c092?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
