As I mentioned in my previous posts on blogging,[...]

A box-and-whisker plot uses simple glyphs that summarize a quantitative distribution with five standard statistics: the smallest value, lower quartile, median, upper quartile, and largest value. This summary approach allows the viewer to easily recognize differences between distributions.
As Mike Bostock explained, this simple force-directed graph shows character co-occurence in Les Misérables. It is a physical simulation of charged particles and springs that places related characters in closer proximity, while unrelated characters are farther apart.
This simple bar chart originally by Mike Bostock is constructed from a TSV file storing the frequency of letters in the English language. The chart uses the following D3 features: d3.tsv – loads and parses data from a tab separated file d3.format – format percentages d3.scale.ordinal – x-position encoding d3.scale.linear – y-position encoding d3.max –[...]
