+# Cascading managed metadata using Graph API (beta)
+
+## Summary
+
+This web part shows how to use the Microsoft Graph APIs (beta) for Taxonomy to get the data.
+
+### Functionality
+
+![Cascading managed metadata](./assets/cmmd.gif)
+
+### Termstore
+
+![Term store](./assets/termstore.png)
+
+## Used SharePoint Framework Version
+
+![SPFx v1.11.0](https://img.shields.io/badge/SPFx-1.11.0-green.svg)
+
+## Applies to
+
+* [SharePoint Framework Developer](https://docs.microsoft.com/sharepoint/dev/spfx/sharepoint-framework-overview)
+* [Office 365 developer tenant](https://docs.microsoft.com/sharepoint/dev/spfx/set-up-your-developer-tenant)
+
+## Pre-requisites
+
+* 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 the term `London` in the image above).

+

+
+## Minimal Path to Awesome
+
+* Clone this repository
+* in the command line run:
+  * `npm install`
+  * `gulp serve`
+
+## 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
+
+### Enhancements
+
+* Currently, this web part supports 2-level cascading. So there is scope to enhance this such that it supports more levels of cascading dynamically.
+* Currently, this web part 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.
