This grouped bar chart is constructed from a CSV file storing the populations of different states by age group. The chart employs conventional margins and a number of D3 features:

d3.csv - load and parse data
d3.scale.ordinal - x-position encoding and color encoding
d3.scale.linear - y-position encoding
d3.format - SI prefix formatting (e.g., “10M” for 10,000,000)
d3.max - compute domains
d3.keys - compute column names
d3.svg.axis - display axes

This simple line chart is constructed from a TSV file storing the closing value of AAPL stock over the last few years. The chart employs conventional margins and a number of D3 features:

d3.json - load and parse data
d3.time.format - parse dates
d3.time.scale - x-position encoding
d3.scale.linear - y-position encoding
d3.extent - compute domains
d3.svg.axis - display axes
d3.svg.line - display line shape

A variation of the example bar chart using a slightly more D.R.Y. style. The visual encoding is represented by two functions and their composition:

The value accessor returns the value (or property) to encode for a given data object.
The scale maps this value to a visual display encoding, such as a pixel position.
The map function represents the composition value ○ scale, mapping from data to display.

Inspired by Andrew Winterman’s post, Tooling for the Lazy Programmer: DRYing up D3.
