Handling Data
Before you start working on the visual part of any visualization, you
actually need data. The data is what makes a visualization interesting.
If you don't have interesting data, you just end up with a forgettable
graph or a pretty but useless picture. Where can you find good data?
How can you access it?
When you have your data, it needs to be formatted so that you can load
it into your software. Maybe you got the data as a comma-delimited
text file or an excel spreadsheet, and you need to convert it to some-
thing such as XML, or vice versa. Maybe the data you want is acces-
sible point-by-point from a web application, but you want an entire
spreadsheet.
Learn to access and process data, and your visualization skills will
follow.
