Microsoft Visio is a vector graphics tool that helps you draw diagrams accurately. Formerly known as Microsoft Office Visio, it’s one of the most popular applications out there for drawing. You can easily install it on your system and utilize its functionalities. It’s a trialware, so you can use it for free for a limited time. However, you’ll need to buy its license if you want to continue using it once the trial has expired. Shapeware Corporation launched the application in 1992. But Microsoft acquired it in 2000 and now it’s a part of MS Office family.
