One way to digitally represent and handle geospatial data is through the use of vector data models. Construct GeoDataFrame from dict of array-like or dicts by overriding DataFrame.from_dict method with geometry and crs, from_features(features[,crs,columns]). The simple visualization has limited utility, as it does not provide much contextual information about the geospatial data. The CRS of a plot refers to the Coordinate Reference System that is used to define the spatial reference of the plots data.
