{"version":"1.0","type":"rich","title":"Assignment 6: Scatterplot with Color Legend ","description":"This D3.js v7 SVG scatterplot displays the relationship between the number of carrier delays and late aircraft delays at various airports, with each point colored by airport name using a ColorBrewer Set3 qualitative scale. The visualization encodes two quantitative variables along the axes and a categorical variable through color, with a manually constructed legend listing the 12 unique airports. The code loads CSV data from a remote GitHub repository, applies linear scales for both axes, and uses d3.axisBottom and d3.axisLeft for tick marks, while the d3-legend library is included but the legend items are appended manually as colored rectangles.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/cc0a6368e48c443381d59523672b8415?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
