MongoDB Charts has added three new geospatial chart types, Choropleth, Geo Scatter, and Geo Heatmap, to its visualization solution. These charts allow users to visualize data on a map, making it easy to expose trends, gain insights, and tell stories using geographic data. The Choropleth chart shades regions based on values, while the Geo Scatter chart shows precise geographical coordinates. The Geo Heatmap charts shaded areas on a map based on combined values of data points within a certain radius. These new chart types can be used to visualize geospatial data stored in MongoDB Atlas or on-premises, and can be customized using various options such as shape schemes, color palettes, and opacity.
