Features

This sample illustrates the following concepts on top of the SharePoint Framework:

Get data terms using Microsoft Graph API (beta).
React Hooks
Using async / await for the async calls
Caching the data in session storage
Usage of PnP SPFx controls (Maps and Placeholder)
Office UI fabric components

Config

Set up the termset structure as shown in the image above.
For the cities, get the required latitude and longitude.
Set the description of the city term as latitude;longitude (as highlighted for teh term London in the image above).

Enhancements

Currently, this webpart supports 2 level cascading. So there is scope to enhance this such that it supports more levels of cascading dynamically.
Currently, this webpart reads latitude and longitude from description of the city terms. If there is a way of getting these from the custom properties of the city terms, then that needs to be implemented.
