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 […]
Venn Diagram
History of Venn Diagram These charts were first mentioned in the 1880 paper entitled “On the Diagrammatic and Mechanical Representation of Propositions and Reasonings” in the Philosophical Magazine and Journal of Science.

Sunbursts emerged as a variant of pie charts, which explains why they are also known as multilevel pies, or, simply, nested pie charts. The earliest known example of pie charts […]

History of Stacked Bar Chart Stacked bar charts evolved out of the bar charts which were first used in the 14th century and later published by William Playfair in The Commercial and Political Atlas to represent export and import of Scotland. Bar graphs evolved to be used for more complex comparisons of data with grouped […]

In 1858 a French engineer named Charles Joseph Minard used pie […]
Circular Barplot
A circular barplot is a plot where each bar is displayed along a circle instead of a line. Here no Y scale is displayed since exact values are written on each bar which could also be represented on interaction with the chart. The chart is popular for its visual appeal however and needs to be […]
Bar Chart
A bar chart or bar graph is a chart that represents categorical data with rectangular bars with heights proportional to the values that they represent. Here one axis of the chart plots categories and the other axis represents the value scale. The bars are of equal width which allows for instant comparison of data. [chartdesc] […]
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 […]
