Comparing pie charts of different sizes could be misleading as people cannot accurately read the comparative area of circles. [7] The usage of thin slices, which are hard to discern, may be difficult to interpret. [7] The usage of percentages as labels on a pie chart can be misleading when the sample size is small. [8]
An example of a chart containing gratuitous chartjunk. This chart uses a large area and much "ink" (many symbols and lines) to show only five hard-to-read numbers, 1, 2, 4, 8, and 16. Chartjunk consists of all visual elements in charts and graphs that are not necessary to comprehend the information represented on the graph, or that distract the ...
Manipulation of the graph's X-axis can also mislead; see the graph to the right. Both graphs are technically accurate depictions of the data they depict, and do use 0 as the base value of the Y-axis; but the rightmost graph only shows the "trough"; so it would be misleading to claim it depicts typical data over that time period.
Statistics, when used in a misleading fashion, can trick the casual observer into believing something other than what the data shows. That is, a misuse of statistics occurs when a statistical argument asserts a falsehood. In some cases, the misuse may be accidental. In others, it is purposeful and for the gain of the perpetrator.
It also shows how statistical graphs can be used to distort reality. For example, by truncating the bottom of a line or bar chart so that differences seem larger than they are. Or, by representing one-dimensional quantities on a pictogram by two- or three-dimensional objects to compare their sizes so that the reader forgets that the images do ...

Simpson's paradox has been used to illustrate the kind of misleading results that the misuse of statistics can generate. [ 7 ] [ 8 ] Edward H. Simpson first described this phenomenon in a technical paper in 1951, [ 9 ] but the statisticians Karl Pearson (in 1899 [ 10 ] ) and Udny Yule (in 1903 [ 11 ] ) had mentioned similar effects earlier.
The Google Chart API allows a variety of graphs to be created. Livegap Charts creates line, bar, spider, polar-area and pie charts, and can export them as images without needing to download any tools. Veusz is a free scientific graphing tool that can produce 2D and 3D plots. Users can use it as a module in Python. GeoGebra is open-source ...
