{"version":"1.0","type":"rich","title":"Task9_Question2","description":"This area chart visualizes US building permits from 1991 to 2020, showing the trend of permit values over time with a purple filled area beneath the line. The visualization uses D3.js v7 to load data from a CSV file via `d3.csv`, then applies `d3.scaleLinear` for both axes and `d3.area` to generate the path. An SVG rendering includes labeled x and y axes using `d3.axisBottom` and `d3.axisLeft`, with the chart drawn in a React-free HTML page.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/797735b16ab5499c8b4c999b9aeb3c1a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
