A

produces graphical displays of patterns and complex relations in large amounts of data

22
Q

infographic types

A

bar chart, histogram (groups numbers into ranges), pie chart, time series chart, sparkling (small embedded line graph illustrates a single trend with no axes or labels as the context comes from the related content)
