{"version":"1.0","type":"rich","title":"Data Visualization Project","description":"This interactive visualization maps the locations of fast food restaurant chains across the United States, using a geographic projection with `d3.geoAlbersUsa`, `d3.geoPath`, and `d3.zoom` to pan and zoom. Clicking a state or a color legend item filters and animates a bar chart showing the top five chains in that region, built with `d3.scaleLinear`, `d3.scaleBand`, and `d3.axisLeft`. Points and bars are rendered as SVG elements with smooth `transition()` animations, while a clickable \"close chart\" button toggles the chart’s visibility.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/aa051de63f324842a655e951e00d8b8c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
