Methods of Encoding Data
Points Help Us To: See and compare unique values in data
Lines Help Us To:
See changes and trends over time and gaps in data
Better see and consider possible relationships in our data, such as correlations
See relative change from a comparison over time.
Add reference values to our visualizations
Bars:
Help us to compare values and order data, for example --ranking
Are versatile and may be arranged either horizontally or vertically based on the overall layout of your visualization and labeling requirements
Must start at zero to correctly show how big one value is compared to another
Bars Also HelpUs See:
Trends over time
Distributions
Complex Comparisons and relative difference from a comparison
Boxes Help Us See: the distribution of data by quartiles
Boxes and Color Help Us Display: Complex Hierarchical Data
Boxes and Color Help Us See:Patterns in multivariate data that can’t be easily shown using bars

Understanding WHYa complex chart type was conceived and, what problem it aims to solve,
is essential to using it correctly.
TREEMAPS (don’t do this!)Were conceived by Ben Shneiderman at the U of MD, to help display complex hierarchies of data. Not simple categorical data, such as Leading Causes of Death, displayed below, that could be displayed, and more easily understood and compared, in a bar graph.
TREEMAPS (do this)Used correctly this graph type allow us to display complex hierarchal data like that in this example. Data by country (largest boxes outlined in white, causes of death (smaller boxes) and changes in the rate per cause from one time period to another (colors and saturation).

Survey Results, Comparisons and Changes Over TimeIn this view we used bullet graphs to display results compared to national results by percentiles, to target for the group and a heat map to show how the survey results have changed over time.
