Waterfall Chart
History of Ben Shneiderman is considered to be the inventor of Treemaps. He created treemaps as a way to visualize a vast file directory on a computer, without taking up too much space on the screen. Treemap has subsequently become an essential method for displaying hierarchical data using nested figures and rectangles in information visualization […]
Scatterplot
History of Scatterplot According to statistician Edward Tufte, more than 70% of all charts in scientific publications are scatterplots. Although no physical evidence remains, the research of Friendly and Denis indicates that the original scatterplot was made in 1833 by the English scientist John Frederick W. Herschel. For his study on the orbits of double […]

The use of a histogram in statistics is to represent a set of continuous, rather than discrete, data. For this reason, Pearson explained that it could be employed as a tool in […]
Bubble Chart
A bubble chart represents data points replaced with bubbles, adding an additional dimension of the data represented through the size of the bubbles. As a variation of a scatter chart, a bubble chart similarly does not use a category axis — both horizontal and vertical axes are value axes. [chartdesc] History of Bubble Chart Bubble […]
Area Chart
An area chart or area graph is based on the line chart but is used to primarily communicate the summation of data rather than represent individual data values, as in line charts. The area between axis and line is usually emphasized with colors, textures or hatchings. The area underneath the line can help one to […]
