Document contrast diagram
Document contrast diagrams use the familiar bubble technique and effective use of colour to contrast topic usage in two bodies of text. Gives a visual summary of the content of two text documents that illustrates shared words, words that are unique to one document or the other, word frequency, relative size of the two documents, distribution of emotional tone within the documents, related words based on co-occurrence, and the most common word in each document segment. This example is the 2007 and 2008 US State of the Union (SOTU) Addresses.
This chart shows a comparison between the level of capitalisation at two time points.
Double document shared word diagrams
Double Document Shared Word Diagrams compare and contrast two documents by showing both the unique and shared vocabulary and its distribution across the two documents of interest. The two columns of squares represent the two documents. The leftmost column of word circles shows the highest frequency non-trivial words found in document 1 but not document 2. The rightmost column of word circles shows those words unique to 2 and the central column shows the words that are common to both.<br />You can also input your text and generate your own visualisation.

Interactive bubble chart
From the website: "This image is a “balloon race”. The higher a bubble, the greater the evidence for its effectiveness. But the supplements are only effective for the conditions listed inside the bubble".
This visualisation shows the volume of respondents with a particular view/experience and, within that, their characteristics. The vertical axes shows the value being measured (in this case annoyance by noisy neighbours). The Horizontal axis shows the numerical value of people responding to a particular level of the given value.
The matrix chart divides the screen into a grid. Rows represent the values in one text column (e.g., political candidate) and columns represent another text column (e.g., states of the US). Each cell then shows a circle or bar that represents the value for its row/column combination (e.g., contribution to Hillary Clinton from New York).
This is a very rich infographic that combines several visualisation types: bubble chart, population pyramid, comparative line charts, a map, pie charts and it is additionally fully annotated. The picture itself is crossed by a line (without reference axis) that communicates the main message of the infographic: the rapid population growth experienced by the UK in recent decades. The supplementary charts display information about population proportions, population densities, age and gender structure, comparison between migration related and “natural” population change, fertility rates during the last 35 years and lastly population changes by government region during 2007-08. The display is very rich and is successful at grabbing’s the reader’s attention by offering an appealing combination of related data.
