The main goal of data visualization is its ability to visualize data, communicating information clearly and effectively. It doesn’t mean that data visualization needs to look boring to be functional or extremely sophisticated to look beautiful.
There are countless possibilities of how to visualize data; but there are many design patterns which are proven to be effective for specific types of data. The following section provides examples of data visualization patterns and a short rationale for when to use them.Independent quantities (bar charts)Comparing the values of independent variablesContinuous quantities (line graphs & stacked area)For data that is continuous, for example when visualizing data over a period of time.Proportions (pie & ring charts)Proportions are used when the data represents parts of a whole.Hierarchies (tree diagrams)Used when the data has a strict hierarchy that needs to be communicated.Networks (diagram map)Network visualizations are used when the most important feature of the visualization is to show which data is connected to each other, as opposed to how.CorrelationsThese are used when each piece of data has two quantifiable variables which can be plotted on a grid.CartographicFor data that is relevant to specific locations or regions which can be plotted on a map.There are more. Don’t limit your scope on these! (see next example)
“Certain visual features operate ‘preattentively:’ they convey information before the viewer pays conscious attention”
There is no visual aid to help us find the values greater than 1.0, forcing us to read all of the data and understand it. Now look at the following table.
StaticThe data visualization does not change over time, and offers no user interaction.AnimatedThe data visualization changes over time - using time as another dimension or variable.InteractiveThe user can interact with the visualization by altering what data is viewed and / or how it is viewed - however the results of interactions are not immediately visible.Direct manipulationThe user can interact with the visualization by altering what data is viewed and / or how it is viewed - and the result of all interactions are immediately visible.
