{"version":"1.0","type":"rich","title":"ColorBrewer","description":"This interactive dashboard presents three coordinated visualizations: a time-series plot of execution metrics, a ColorBrewer palette selector, and a bar chart of World Happiness rankings. The time-series chart uses d3.line and d3.scaleTime to render trends, with color-coded dots distinguishing TRUE/FALSE results. Clicking any palette swatch updates the happiness chart’s color scale via d3.scaleQuantize, which dynamically recolors the top-20 country bars. Tooltips appear on hover for both charts, built with D3 v7’s event handling and CSS transitions.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ee5318826cfd44ee8328e96803682dde?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
