There are a lot of striking examples of bad and misleading visualizations out there. Even specific websites dedicated to the topic can be found. Yet, most of them only discuss charts and maps. Examples for bad 3D visualizations of spatial data (medical, flow, engineering, biological, climate, wheater, ...) are really hard to find.
Does anyone know of a good source for those?

In a couple of hours, my colleague Simon and I will be on the way to the International Symposium on Vision, Modeling, and Visualization (#VMV) in Braunschweig.
Simon will present our work on using GPU-accelerated texture compression for efficient vector field visualization.
If you are interested, the paper is already available via Eurographics:
Really looking forward to the other presentations and conversations ahead.
Exploring the Venturi effect.
A simulation was performed to create this model which depicts streamlines within a tube. The lines are coloured to show that the pressure at the throat section is lower (blue) than the pressure at the inlet or outlet sections (red).

The Venturi effect occurs when the velocity of a fluid increases as the area of the container it flows through decreases. The pressure in the tube decreases as the fluid flows through the narrow section due to this increase in velocity. A simulation was performed to create this model which depicts streamlines within a tube. The lines are coloured to show that the pressure at the throat section is lower (blue) than the pressure at the inlet or outlet sections (red). Particle movement is based on velocity measured during the simulation. The particles travel faster as the rate of flow increases in the narrower section of the tube. They slow again as the tube widens. - Exploring the Venturi effect - 3D model by famousandfaded
