This gallery shows:
* A [[bubble chart]] is a two-dimensional scatterplot where a third variable is represented by the size of the points.
* A [[Pie chart#Polar area diagram|polar area diagram]], sometimes called a Coxcomb chart, is an enhanced form of pie chart developed by [[Florence Nightingale]].
* A [[radar chart]] or "spider chart" or "doi" is a two-dimensional chart of three or more quantitative variables represented on axes starting from the same point.
* A [[waterfall chart]] also known as a "Walk" chart, is a special type of floating-column chart.
* A [[Treemapping|tree map]] where the areas of the rectangles correspond to values.  Other dimensions can be represented with color or hue. Smaller areas go to the bottom right corner.
* A [[streamgraph]], a stacked, curvilinear area graph displaced around a central axis
* A GapChart, a time series chart showing evolving gaps and equalities between series. Other dimensions can be represented with color or hue.
