I hope you got a chance to read the mail about the charts in Coda and try some out. Was looking for reactions -
What did you like?
What would you improve?
Coda now has charts.
Map trends. Spot outliers. Show those sales going up and to the right.
Think of charts as just another view of a table. The more visualizations you add, the better you can understand your data and help others understand it too.
