Building Interactive Mapping Apps with Gatsby

Interactive maps serve as a powerful tool for data visualization and analysis, as demonstrated by the COVID-19 map from Johns Hopkins University. Gatsby, a framework built on React, simplifies the creation of such mapping applications by providing tools like Leaflet and React Leaflet. These tools allow developers to integrate geospatial data directly into the Gatsby pipeline, enabling dynamic generation of location data and automatic page creation. Gatsby's Command Line Interface supports Starters to easily scaffold new apps, while its Recipes feature facilitates adding functionalities, such as maps, to existing projects. A practical example of this capability is demonstrated through a restaurant mapping app, which dynamically displays geographic locations on a custom map and creates pages for each location. This process leverages Gatsby's GraphQL API and useStaticQuery React hook to manage data effectively.
