## LGraphCanvas
LGraphCanvas is the class in charge of rendering/interaction with the nodes inside the browser.
## LGraphCanvas settings
There are graph canvas settings that could be defined or modified to change behaviour:
* **allow_interaction**: when set to `false` disable interaction with the canvas
* **drag_mode**: when set to `true` and `allow_interaction` is `false`, allow individual nodes with `flags.allow_interaction` set to `true` to be interacted with
### Canvas Shortcuts
* Space - Holding space key while moving the cursor moves the canvas around. It works when holding the mouse button down so it is easier to connect different nodes when the canvas gets too large.
* Ctrl/Shift + Click - Add clicked node to selection.
