I used the data from Wikipedia’s “Color” entry for different languages. My assumption was: "Different languages have different ways to describe color.” (Scroll Down to Start) The Chinese entry has 250+ different colors. The Hue-Saturation-Lightness (HSL) model is a 3D model that can be projected on a 2D space. Using Hue as an angle, we can set either Saturation as the radius . . . or Lightness as the radius.

Here is the English Dataset, keeping Lightness as a constant . . . or keeping Saturation as the constant. Comparing the two datasets, you can see that English has a richer entry for color names. However, it's always worth asking: Is this the best model to represent our dataset? Notice that the Chinese and English names for colors share a common structure of "noun/adj + base color": Here are all the colors with 青 in their names. Green Honey. Peer 2 Peer University.

Visualizing Algorithms. The power of the unaided mind is highly overrated… The real powers come from devising external aids that enhance cognitive abilities.

Visualizing Algorithms

—Donald Norman Algorithms are a fascinating use case for visualization. To visualize an algorithm, we don’t merely fit data to a chart; there is no primary dataset. Instead there are logical rules that describe behavior. This may be why algorithm visualizations are so unusual, as designers experiment with novel forms to better communicate.

But algorithms are also a reminder that visualization is more than a tool for finding patterns in data. #Sampling Before I can explain the first algorithm, I first need to explain the problem it addresses. Light — electromagnetic radiation — the light emanating from this screen, traveling through the air, focused by your lens and projected onto the retina — is a continuous signal. This reduction process is called sampling, and it is essential to vision. Sampling is made difficult by competing goals. Here’s how it works: DATACOLLIDER - MIT Senseable City Laboratory. Tableau.
