{"version":"1.0","type":"rich","title":"Assignment 6: Bar Chart with Color Legend ","description":"This example presents a bar chart of carrier delays by airport, with bars colored on a sequential blue scale and a corresponding color legend. The chart loads data from a remote CSV file using `d3.csv`, scales the x-axis with `d3.scaleBand` and the y-axis with `d3.scaleLinear`, and renders rectangles in SVG. The color encoding uses `d3.scaleSequential` with `d3.interpolateBlues`, while the legend is generated via the `d3-legend` plugin’s `d3.legendColor`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e37c583560fb4bd1a7cfd57dec3e8efd?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
