{"version":"1.0","type":"rich","title":"Assignment #2 Building Dashboard","description":"This dashboard visualizes how AI tool usage relates to productivity and work/study hours among students and professionals, using a dataset from Kaggle. It presents four interactive charts: a bar chart showing AI tool popularity, a pie chart for user type distribution, a line chart for productivity against work/study hours, and a scatter plot of AI usage versus productivity. Built with D3.js v7, the visualization uses SVG rendering and employs `d3.rollup` for data aggregation, `d3.scaleBand` and `d3.scaleLinear` for scales, and `d3.axisBottom` for axes. The code handles missing numeric values by substituting column means and filters out incomplete categorical rows before rendering.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/30ac03a0c1c94ee2bd18bf73e4995164?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
