{"version":"1.0","type":"rich","title":"first ","description":"A US state heatmap visualizes minimum wage values over time. Users select among four wage metrics—effective minimum wage, effective minimum wage in 2020 dollars, federal minimum wage, or state minimum wage—from a dropdown. D3 v7 renders an SVG grid with years on the x-axis and states on the y-axis, where each rectangle's color is mapped via `d3.scaleSequential` with `d3.interpolateTurbo`. Hovering a cell triggers a tooltip showing the state, year, and precise numeric value. Data is loaded remotely from a CSV hosted on GitHub.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a57a6d8e5d474aa18ef0f45e0903b023?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
