The Flare visualization library as a circle packing chart. Note the use of the
sort property in the pack transform to sort the data by the size column.
This results in more efficient packing than using the data in its original order. Data linked from vega-datasets.
The Flare visualization library as a hierarchical treemap. The labels have been
rotated to follow the aspect ratio of the blocks. A
paddingOuter creates a margin around groups of
child blocks, leaving space for a label. Leaf node labels are scaled according the the block size. Data linked
from vega-datasets.
The Flare visualization library as a sunburst chart with rotated labels. Data linked

The 2012 US Presidential election results by county as faceted treemaps. Each
state is a separate treemap, with each county sized according to its total population, and colored according
to the percentage of votes for Obama (blue) to Romney (red). The heights of the blocks also represent total
population. Only the continental US is included and the states are ordered alphabetically. The labels have been
rotated to follow the aspect ratio of the blocks, and scaled to the block size (with a maximum font size). The
word "County" has been removed from each county for clarity. Data linked from SandDance.
An adjacency matrix showing character co-occurrence in Les Misérables. This
visualization shows character relationships in Victor Hugo's novel, Les Misérables. The data is a network, where
nodes represent characters in the novel, and edges represent two characters appearing in the same chapter.
While this data can be drawn as a node-link graph, this chart is an adjacency matrix. Since co-occurrences are
not directed, the chart is symmetrical. The characters are ordered according to a clustering algorithm which
detects character communities, rather than alphabetically, or by total co-occurrences. D. E. Knuth, The Stanford GraphBase: A

Population Pyramid of US Census from 1850 to 2000. Note the missing data for year
1890. U.S. population counts by age group (0-90+ in 5-year intervals) and sex for each decade between 1850 and
2000, collected and harmonized from historical census records by IPUMS USA. IPUMS updates and revises datasets
over time, which may result in discrepancies with current IPUMS data. Steven Ruggles, Katie Genadek, Ronald Goeken, Josiah Grover, and

US Polio cases from 1928 to 1968. This is a 3D version of a chart which appeared in a
Wall Street Journal article. The blocks
are sized and colored by cases per 100,000 people. The vaccine was introduced in 1955.

A 3D Lissajous curve. The curve is defined by three parametric
sin
functions, and drawn as a line with rows line segments, and thickness strokeWidth.
Try varying a, b, and c for different effects.
The color can be varied using a scale along the t field (uncomment the _fill).
