This dashboard visualizes AI usage patterns and productivity among students and professionals, with data sourced from a Kaggle dataset. It presents four linked charts: a bar chart showing AI tool popularity, a pie chart for user type distribution, a line chart examining productivity against work or study hours, and a scatter plot relating AI usage to productivity. Built with D3 v7, the visualization uses SVG rendering, `d3.rollup` for data aggregation, and scales like `d3.scaleBand` and `d3.scaleLinear`, with a custom axis and rotated labels.
