{"version":"1.0","type":"rich","title":"Total Crimes Map","description":"This map visualizes the total violent crime rates across U.S. metro areas from 1975 to 2015, with each city represented by a semi-transparent circle positioned by latitude and longitude. The visualization layers a geographic outline of U.S. states over the data points, using a color encoding to differentiate crime rates and years. Built with Vega-Lite and rendered through the vega-lite-api, the map employs an Albers USA projection and fetches crime data from a CSV file, while state boundaries come from a TopoJSON source. The tooltip feature provides detailed city information on hover.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3494575bacf24faa8fae4d46c9fad12d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
