I am a visual learner. When I try to teach something, I naturally like to use visual examples. That usually involves me working for hours to create flowcharts in Google Docs using the drawing program. Yes, it works, but it's a very cumbersome way to create a flowchart. Thankfully, I recently discovered Lucidchart.

Lucidchart is an on-line service that provides a free way to create flowcharts quickly and easily. Once the flowchart is created, items can be dragged around, resized and modified while still staying connected. I used Lucidchart for this month's Open-Source Classroom column, and if you need to create a quick flowchart, I recommend you give it a try as well.

Lucidchart provides its service for free, but there also are paid tiers that give you more options, such as importing and exporting Visio documents and so on. There certainly are other more powerful charting tools available, but few are as simple and quick to use.
