This fun and engaging event showcases examples of egregious perceptual, cognitive, and conceptual errors in visualization, presented by members of the VIS community. Examples from our own work, from published papers, and from the internet highlight the many ways the visual representation can misrepresent the underlying phenomena in the data. This is a great opportunity for amusement and for learning, and every year we walk away with a smile on our faces and a deeper sense of responsibility that may one-day impact the world.

Call for Participation

VisLies is an open forum for anyone to present their favorite visual misinformation. Make VisLies more fun for yourself and everyone else by sharing your favorite (or most deplored) ways to misrepresent data.


VisLies is looking for any examples of visualization examples or techniques that take honest data and present them in ways that mislead or confuse the viewer. We are looking for presenters to provide example visualizations, produced from either others or themselves, that demonstrate how that visualization deceives. These examples help teach us in an entertaining way. Common examples of misleading visualizations and techniques include

The list goes on. Really, anything you find that detracts from the data is fair game.


There are lots of great reasons to present at VisLies.


Becoming part of VisLies is easy. Simply send an email to with your name and a note that you want to present. That’s it.
