Data Stories: Understanding Histograms, Joyplots, and Sorting Algorithms

A complete toolbox for data visualization contains many methods for sorting and displaying data.

Creating a Histogram

Histogram

‎Histograms are a common way to aggregate data and show value distribution. This interactive site explains in detail how to construct them.

 

Showing Distribution Over Time

Joyplot

One way to expand on the information in a histogram is the visualization known variously as a stacked distribution, frequency trail, or joyplot.

 

Ways to Sort Data

Sorting algortihms

This series of animated images illustrates how various sorting algorithms work. There are Wikipedia links interspersed in case you aren’t familiar with the terms.
