{"version":"1.0","type":"rich","title":"Area Chart","description":"This area chart visualizes the average life expectancy over time, using a blue filled region beneath a line to emphasize the trend. Built with D3 v7, the SVG graphic relies on `d3.area()` to generate the path, with linear scales for both axes and data parsed from a CSV file. Axis ticks are added via `d3.axisBottom` and `d3.axisLeft`, while the chart's dimensions are set with explicit margins for clear presentation.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1868f1251a85417591a6486dc0453deb?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
