{"version":"1.0","type":"rich","title":" Activity6_Question3","description":"This scatter plot visualizes city data, mapping population on the x-axis against area on the y-axis, with each point colored by region using a categorical color scale. The code loads a CSV file from GitHub, parses it, and renders circles in an SVG using D3 v6 APIs such as `csv`, `scaleLinear`, `scaleOrdinal`, `axisLeft`, `axisBottom`, and `entries`. A legend, built with appended rectangles and text, identifies the region colors. The visualization uses the browser’s full window dimensions and positions axes with margin conventions.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5afdfe6e74b44e8d8dca34aa90f774dc?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
