{"version":"1.0","type":"rich","title":"Project Increment 2","description":"This heatmap displays pairwise Pearson correlations among 18 numeric columns from the World Happiness Report 2021 dataset, using a diverging color scale from blue (negative) to red (positive) via `d3.scaleDiverging` and `d3.interpolateRdBu`. Each cell represents the correlation between two variables, with tooltips revealing exact r values. The code loads CSV data with `d3.csv`, computes correlations pairwise while ignoring missing values, and renders an SVG matrix with `d3.scaleBand` for axes and positioning.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e7c7fcf8346d4a97a75cddd6bbfb24ce?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
