{"version":"1.0","type":"rich","title":"A7 - Heatmap in D3","description":"This heatmap visualizes the frequency of tropical storms in the Atlantic from 1995 to 2019, with years on the x-axis, storm names on the y-axis, and color intensity indicating frequency. It uses D3 v6 to construct an SVG heatmap, reading data from a CSV file and applying the Inferno color scale. Tooltips display exact frequencies on hover, while a gradient legend clarifies the color mapping. The chart includes axis labels and a title, making the distribution of storm activity over time and by storm type readily apparent.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/17c4e07ce687423aae8b5bc67c5d8659?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
