+This demo program shows how to create a single Matplotlib graph and show it in a GUI window.
+
+Note the it lacks an "Event Loop".
+Normally instead of:
+
+```python
+event, values = window.read()
+```
+
+You would see an event loop:
+```python
+while True:
+    event, values = window.read()
+    if event is None:
+        break
+    ```
+    
+If you wanted to show multiple graphs or have other GUI elements, then you would replace that line of code with the event loop above and you'll have a "Normal" PySimpleGUI window.
