![]() ![]() The scatter plot was the clear winner, suggesting that people are surprisingly proficient at looking at a large number of data points on a plane and understanding the information. They wanted to test which different chart types people understand most accurately and quickly. In the 1980s, William Cleveland and Robert McGill made a notable discovery regarding scatter plots. Suddenly, a new visualization type was born. Once popularized, it didn’t take long for Karl Pearson to coin the term “scatter plot” in 1906. He began using scatter plots to study a variety of correlations, such as the heights of parents versus their children. However, it was Francis Galton (50 some years later) who popularized this type of visualization. Herschel published a study on the orbit of stars, which included a visualization of single points plotted on a Cartesian plane. This coordinate plane forms the foundation for the scatter plot you can’t have this diagram without it.Įven with the invention of the Cartesian plane, it would take over 200 years before the first scatter plot appeared. To understand the origins of this visualization, we have to look at the invention of the Cartesian plane in 1600. The history of the scatter plot, however, takes a different path. Many of these major chart types owe their origins to William Playfair. Scatter plots are a common diagram option, not far removed from bar charts or line graphs in popularity and usage. ![]()
