Venn Diagram Plotter

Venn Diagram Plotter is an easy-to-use software application that enables you to seamlessly put together Venn diagrams by configuring circle parameters, and save them as photos.

Simple setup and interface

The setup procedure doesn't take a long time to finish, and the only notable aspect about it is that Venn Diagram Plotter requires .NET Framework installed to run properly. It's wrapped in a classical interface that doesn't contain attractive graphical elements but it's simple to navigate.

Define parameters for two or three circles

Two circles with different colors are shown by default in the design and you can change their colors, adjust their overlap, as well as modify their default size or total number of items included in each circle.
A third circle may be listed alongside the other two, which makes room for additional options. You can set the overlap and overlap colors between any two circles, rotate the whole image, or adjust the opacity level.

Save the plot as an image file

It's also possible to zoom in and out, tweak the horizontal and vertical offset, update counts, compute the optimal region counts, as well as define the total unique item count or count overlapping for all three circles.
The diagram can be copied to the Clipboard as an image or saved to a BMP, PNG or SVG file. Plus, you can save settings to apply them later in similar projects.

Evaluation and conclusion

We haven't come across any difficulties in our tests as far as stability goes, thanks to the fact that the application didn't hang, crash or display error messages. Its impact on the PC's performance was minimal, since it needed low CPU and RAM to work properly.
Although it doesn't integrate rich features and its interface looks outdated, Venn Diagram Plotter supplies you with straightforward and effective means of designing and saving Venn diagrams, and it can be handled by any user. Plus, it's free.
