Man handing drawing a chart on a whiteboardHuman beings are a visual species. We mostly interact with the world through our eyes and that’s why they say a picture is worth a thousand words. But what if you want to use words to make a picture? What if you want to put these words in a visual space that is more easily comprehended by our large primate brains? That’s where charts, diagrams, mind maps, and flowcharts can be the answer.

Of course, you could whip out a blank piece of paper and start drawing out these diagrams using a ballpoint pen, but that’s not the smart way to do it. The paper and pen diagram isn’t easily modified, nor is it easily shared. It’s hardly reasonable to try and collaborate in real time on one of these diagrans with a friend who is in another part of the office, let alone another part of the world. Thankfully, the Internet has once again come to the rescue.

We previously discussed just five online flowchart tools, but we thought that list was well worth expanding. After all, there are more to mental pictures than flowcharts, so let’s have a look at a huge array of websites where you can create all kinds of digital charts and diagrams. Visualizing the mental process has never been this efficient (or fun).
