{"version":"1.0","type":"rich","title":"Day / Hour Heatmap","description":"This heatmap visualizes concurrent user sessions across days of the week and hours of the day, inspired by Trulia Trends. Using D3 v3 and SVG, it renders a grid where each cell represents one hour of one day, colored by the recorded session count from a development environment. The chart includes a color legend to map values to hues and an animated transition that cycles through two datasets (data.tsv and data2.tsv), smoothly updating the cell colors to compare patterns between the two periods. Rows correspond to days (1–7), columns to hours (0–23), and the color scale highlights peak usage times, with the animation providing a temporal comparison of activity distributions.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-53e05f8ba4500321834036343c35d3ce?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
