graph: visualization that contain exact values charts: simplistic, less precise visualization figure: not a table table: rows, column, numeric (Caption go above tables but below figures)
Disadvantage
not precise
spend time comparing two charts
Only use
value add up to 100%
small number of items
audience does not care about exact difference
able to read black / white
non-technical audience
Effective Caption
number your visualization, using independent number schemes for tables and figures
describe what the visualization contains—in particular any items that are being compared
explain the units of measurement, including the high and low points of any scales used
optionally include a one-sentence summary of the visualization’s main story
