{"version":"1.0","type":"rich","title":"Activity 7.1.2","description":"This area chart visualizes LEGO sales over the past decade, showing a smooth, curved trend of annual revenue growth. The visualization uses D3 v5 APIs, including `area` and `line` generators with `curveBasis` for smooth interpolation, along with `scaleTime` and `scaleLinear` for axes. Gridlines and axis labels are rendered via `axisBottom` and `axisLeft`. Data is loaded from a CSV hosted on GitHub, parsed with `timeParse`, and displayed as an SVG with a steelblue filled area and darkblue line.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/bfe7760572f347e5a3992616db27ffa9?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
