{"version":"1.0","type":"rich","title":"Fork of Assignment 6: Bar Chart with Color Legend ","description":"This example shows carrier delay counts for various airports in a bar chart, with each bar colored on a blue sequential scale to encode delay severity. The visualization loads data from a remote CSV file using `d3.csv`, then renders an SVG with `d3.scaleBand` for the x-axis and `d3.scaleLinear` for the y-axis. It uses ColorBrewer’s Blues palette via `d3.interpolateRgbBasis` to create the color mapping, and the `d3-legend` library’s `d3.legendColor` to display a matching color legend. Axis labels are rotated with SVG attributes, and bars use `d3.axisBottom` for x-axis ticks.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b1794fe910694a9387313264b4ef41fd?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
