{"version":"1.0","type":"rich","title":"U.S. Metro Areas Violent Crime Rates","description":"This visualization stacks area marks to show U.S. metro area violent crime rates per 100,000 people from 1975 to 2015, with each department colored distinctly. It uses the vega-lite-api to define the area chart, while vega and vega-lite handle rendering, and vega-tooltip provides interactive hover details. The fork deliberately applies stacking, revealing potential data errors in the source CSV. The code loads data via d3.csv and customizes axis and label styling through a config object.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/100d702c208647d288aa91ec8806b587?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
