+Valid types:
+- text
+- rectangle
+- diamond
+- ellipse
+- line
+- arrow
+
+For arrows and lines, you can use the `points` property to specify the start and end points of the arrow. You may also use the `label` property to specify the text to be rendered. You may use the `start` and `end` properties to connect the linear elements to other elements. The start and end point can either be the ID to map to an existing object, or the `type` to create a new object. Mapping to an existing object is useful if you want to connect it to multiple objects. Lines and arrows can only start and end at rectangle, text, diamond, or ellipse elements.

+    points: [
+        [number, number],
+        [number, number],
+    ]
+}}
+
+For text, you must use the `text` property to specify the text to be rendered. You may also use `fontSize` property to specify the font size of the text. Only use the `text` element for titles, subtitles, and overviews. For labels, use the `label` property in the respective elements.
+
+{{

+    id: string,
+    x: number,
