{"version":"1.0","type":"rich","title":" Assignment 4: Bar Chart with D3","description":"This bar chart visualizes the top 10 airports ranked by total carrier delay minutes, using a logarithmic y-scale to accommodate wide value ranges. The visualization loads CSV data via `d3.csv`, aggregates values with `d3.rollup`, and renders SVG bars using `d3.scaleLog` and `d3.scaleBand`. Interactive tooltips appear on hover, displaying the airport code and delay count, while axes are generated with `d3.axisBottom` and `d3.axisLeft`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/0132f80598a44836973e4e4cd1425f4f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
