{"version":"1.0","type":"rich","title":"Colm Lang A4 | Heatmap","description":"This heatmap visualizes the average share of renewable energy production (as a percentage of total generation) across ten European areas from 2000 to 2020. Using d3.csv to load the data, it maps years along the x-axis and areas along the y-axis, coloring each 30-pixel cell with d3.interpolateRgb.gamma to encode share values. On hover, each cell reveals its exact percentage via a text label. The chart is rendered as an SVG with d3.axisBottom and d3.axisLeft for the axes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/281140a3a59c4a24bedfd88d831a6d01?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
