Data visualization
Data visualization consists of presenting information and data graphically to synthesizing complex information and understanding patterns and exceptions presented in the data. Data visualization should not be used as decoration.
Which chart to use
The type of chart you use depends primarily on two things: the data you want to communicate, and what you want to convey about that data. These guidelines provide descriptions of various different types of charts and their use cases.
Comparison
Compare data between multiple distinct categories.
Change over time
Show data over a period of time, such as trends or comparisons across multiple categories.
Relationship & Distribution
Show the relationship between two or more variables or the frequency at which data occurs.
Control
Used in processes to track the evolution of a variable against one or more values of reference.
Part-to-whole
Show how partial elements add up to a total.
Dashboards
Operational dashboard
Use it to provide information that demands immediate user action and time-sensitive data, such as data monitoring. This kind of dashboard is constantly updating.
Analytical dashboard
Use analytical dashboards to help users take future actions, investigate or analyze data. It updates less frequently than the operational dashboard (eg: 1 time a day). Learn more about dashboard types at Nielsen and Norman group website.
