{"version":"1.0","type":"rich","title":"yi xiao heatmap","description":"This heatmap displays earthquake activity across U.S. states over time, with years on the y-axis, states sorted by total count on the x-axis, and color intensity representing earthquake frequency. The visualization uses a red color scheme to highlight higher values, with tooltips showing the exact state, year, and count on hover. Built with Vega-Lite and the vega-lite-api, it loads data from a CSV file containing earthquake counts by state and year, transforms it into long format, and renders a markRect chart with configured styling.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d7b955c667424103bc99d09b5f88c072?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
