Junk Charts
Dona Wong, whose graphics book I reviewed two years ago ( link ), has recently joined the New York Fed to lead an effort to visualize data. This is exciting because consumers are unlikely to learn anything from Excel spreadsheets, HTML tables, etc. which are the typical formats of public data. One of their efforts is visualization of mortgage delinquency data in the Tri-state and Long Island regions ( link ). This animation reminds me of the CDC obesity map, to which I gave a positive review in 2005 ( link ). This type of chart is great for revealing the evolution of a metric over time and over space.

jqPlot - Pure Javascript Plotting
Computation and drawing of lines, axes, shadows even the grid itself is handled by pluggable "renderers". Not only are the plot elements customizable, plugins can expand functionality of the plot too! There are plenty of hooks into the core jqPlot code allowing for custom event handlers, creation of new plot types, adding canvases to the plot, and more!
