Completed Tornado Diagram. Tornado diagrams, also called tornado plots, tornado charts or butterfly charts, are a special type of Bar chart, where the data categories are listed vertically instead of the standard horizontal presentation, and the categories are ordered so that the largest bar appears at the top of the chart, the second largest appears second from the top, and so on.
Based on my experience using other interactive graphs online, I expected that when I moused over a point in a line graph, I'd be told what that point's value was, but such a feature doesn't exist.
The usage of percentages as labels on a pie chart can be misleading when the sample size is small. [8] Making a pie chart 3D or adding a slant will make interpretation difficult due to distorted effect of perspective. [9] Bar-charted pie graphs in which the height of the slices is varied may confuse the reader. [9]
The bars can be plotted vertically or horizontally. A vertical bar chart is sometimes called a column chart and has been identified as the prototype of charts. [1] A bar graph shows comparisons among discrete categories. One axis of the chart shows the specific categories being compared, and the other axis represents a measured value.
This Q–Q plot compares a sample of data on the vertical axis to a statistical population on the horizontal axis. The points follow a strongly nonlinear pattern, suggesting that the data are not distributed as a standard normal (X ~ N(0,1)). The offset between the line and the points suggests that the mean of the data is not 0.

OLAP clients include many spreadsheet programs like Excel, web application, SQL, dashboard tools, etc. Many clients support interactive data exploration where users select dimensions and measures of interest. Some dimensions are used as filters (for slicing and dicing the data) while others are selected as the axes of a pivot table or pivot chart.
An ordered graph is a graph with a total order over its nodes.. In an ordered graph, the parents of a node are the nodes that are adjacent to it and precede it in the ordering. [1]
