{"version":"1.0","type":"rich","title":"D3 - Qualitative color scale Scatterplot","description":"This example visualizes global agricultural productivity with a qualitative color scale, plotting wheat production against a pest control metric. Each circle represents a data point, with colors encoding the year (2015–2021) using an ordinal scale from d3.scaleOrdinal. The scatterplot uses d3.csv to load data and d3.axisBottom/axisLeft for axes, while a legend from d3.legendColor clarifies the year mapping. The SVG rendering applies linear scales for positioning and radius, though circle size remains fixed at 8 pixels despite the size scale being defined.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/37275e6e6ab343d982ceff61d950a39e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
