+Draw pie charts and line charts in iOS apps
+
+Todo for line chat
+------------------
+Use gesture/tap to show the value label (or mild statistics) for a data point.
+Further break out colors for customization of background, x/y labels, and shadows.
+Allow legend labels to appear on either the right or left side of the chart (or not at all).
+Use the rendered string width of the legend labels to determine right/left side margin.
+If a legend string is significantly long (200% percentage of default margin width?), truncate or abbreviate it to X characters.
