{"version":"1.0","type":"rich","title":"Frisco Schools","description":"Frisco Schools visualizes the construction timeline of schools in Frisco, Texas, from 1986 to 2017. Each row represents a year, with colored rectangles marking individual schools—blue for elementary, yellow for middle, and red for high schools. The visualization uses D3.js v5 with SVG and animation, employing `d3.nest()` to group data by year, `d3.scaleTime()` for the y-axis, and `d3.csv()` to load the dataset. Interactive tooltips appear on mouseover via D3 transitions, while unused years are marked in gray.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b6fa444a369e41d69e92a2850297ab93?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
