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.tsv - 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

This choropleth encodes unemployment rates from 2008 with a quantize scale ranging from 0 to 15%. A threshold scale is a useful alternative for coloring arbitrary ranges.

This diagram shows age distribution in the Australian Capital Territory from 1971 through to 2059 (projections from 2009-2059).

Use the arrow keys to observe the changing population in 5 year increments. The blue bars are the male population, while the pink bars are the female population; the bars are partially transparent so that you can see how they overlap, unlike the traditional side-by-side display which makes it difficult to compare the relative distribution of the sexes.

• Code forked from mbostock's Population Pyramid example.
