streamgraph

similar to stacked barcharts but lookup and comparison can be difficult

multiple quantitative/ordinal attributes

use of parallel axes - positive correlation is represented with parallel lines and negative correlation is represented with crossing lines

data points in the hundreds, attributes up to 12

radial bar charts what

one categorical attribute and one quantitative attribute

radial bar charts how

use of radial position (angle) and length

radial bar chart con

angle as a visual variable is less accurate than rectilinear position

pie chart, doughnut chart, polar area chart what

one categorical attribute and one quantitative attribute

pie chart limitiation 1

angle and arc length are hard to estimate

pie chart limitation 2

sizes of irregular areas are hard to estimate

doughnut charts, polar area chart how

area mark in radial layout

polar area chart, doughnut chart, pie chart why
