History of Data Visualization
Prior to the 17th century, data visualization existed mainly in the realm of maps, displaying land markers, cities, roads, and resources. As the demand grew for more accurate mapping and physical measurement, better visualizations were needed.
In 1644, Michael Florent Van Langren, a Flemish astronomer, is believed to have provided the first visual representation of statistical data.
A Timeline is a graphical way of displaying a list of events in chronological order. Some Timelines work on a scale, while others simply display events in sequence.
