{"version":"1.0","type":"rich","title":"d3 bar sequential","description":"This example visualizes the distribution of infectious diseases in 1968 using a sequential bar chart, with each bar’s height and color intensity encoding the number of infections. The chart employs a sequential color scale based on ColorBrewer’s OrRd scheme, mapping values from 0 to 150,000, and includes a legend generated with the d3-legend library. The visualization is rendered as SVG using D3 v6, with axes, labels, and a dark background for contrast. The data, simplified from the CORGIS Global Development dataset, is loaded from a CSV file, and the chart uses `d3.scaleBand` for the categorical x-axis and `d3.scaleLinear` for the quantitative y-axis.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2481401bbd4a4ee08e04b8efd2ff6c66?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
