5 Plots on Gender You Have to See (Weekly Plotly Roundup)
We’ve posted a new roundup of the latest and greatest Plotly plots! Check out our full post with the interactive plots embedded to find more awesome content.
The data for this area plot comes from a study in which researchers sent thousands of identical emails to professors across the country and signed them with names signalling different genders and ethnicities. Basically, in every department outside the Fine Arts, emails signed with a “white male” name received more attention than almost any of the others — even when the professors were themselves women or members of a minority group.

Adding just a few polymers to a liquid can substantially change its behavior. The presence of polymers turns otherwise Newtonian fluids like water into viscoelastic fluids. When deformed, viscoelastic fluids have a response that is part viscous—like other fluids—and part elastic—like a rubber band that regains its initial shape. The collage above shows what happens to a thinning column of a viscoelastic fluid. Instead of breaking into a stream of droplets, the liquid forms drop connected with a thin filament, like beads on a string. In a Newtonian fluid, surface tension would tend to break off the drops at their narrowest point, but stretching the polymers in the viscoelastic fluid provides just enough normal stress to keep the filament intact. If the effect looks familiar, it may be because you’ve seen it in the mirror. Human saliva is a viscoelastic liquid! (Image credit: A. Wagner et al.)
