To read ESRI shapefiles in Observable Framework, convert the `.shp` and `.dbf` files into GeoJSON FeatureCollection objects. This allows you to load geographical boundaries and attribute data directly into your Observable projects.

Converting a shapefile to GeoJSON for mapping involves extracting geometry and attribute data from `.shp` and `.dbf` files. The resulting GeoJSON FeatureCollection can then be used directly for geospatial visualization tasks.

Yes, you can use D3, Observable Plot, and Leaflet to visualize shapefile data. The shapefile must first be converted into GeoJSON format, which these libraries natively support for rendering interactive maps and spatial data.

The best way to load geographic boundaries from a shapefile in Observable is to parse the `.shp` and `.dbf` files into a GeoJSON FeatureCollection. This standard format easily integrates with mapping libraries for display.

Yes, you need both `.shp` and `.dbf` files to extract shapefile attributes. The `.shp` file contains the geometry, while the `.dbf` file stores the attribute data, and both are converted together into GeoJSON.
