draw.io (https://www.draw.io/) is a quick and simple web-based app to create:
- network diagrams
- venn diagrams
- room layouts
…and much more.
Diagrams can be saved directly to your Google or One Drive as HTML files to keep the file size small and exported to your desktop as a .png, .jpg .pdf or .svg file.
You can also embed your diagrams directly in to your Blackboard site using the <iframe> function.
Creating diagrams couldn’t be easier.
