ASCII Art Diagrams With ditaa

Perhaps you thought ASCII art was an extinct form of graphics. This cool little app illustrates that you may be mistaken. Draw your own conclusions.

Old technologies never die. Instead, their range of application shrinks. Or maybe it grows when conditions change.

ASCII art, drawing pictures with fixed-width plain text characters, is no longer how many people want to produce diagrams. Just fire up Adobe Illustrator and you get incomparably more resolution of expression.

And yet there are times when ASCII art comes in handy. You can, for example, paste it into source code files. Someone more familiar with Emacs than Illustrator may be able to produce a simple diagram in the former faster than the latter. And it can be relatively easy to programmatically produce a large number of ASCII art diagrams, depending on the nature of the diagrams.

It’s also possible to use ASCII art as a way to specify nicely rendered images. I’ll show how to do that with ditaa below.

Here’s an ASCII version of the conjugate prior diagram I made some time ago:


                          +-------------+
                          |             |
                          | Exponential |
                          |             |
                          +-------------+
                                 |
                          lambda |                                                          
                                 v
+-------------+           +-------------+           +-------------+
|             |   tau     |             |   lambda  |             |
|  Lognormal  |---------->|    Gamma    |<----------|   Poisson   |
|             |           |             |---+       |             |
+-------------+           +-------------+   |       +-------------+
      |                          ^   ^      | beta
      |                          |   |      |
      |                          |   +------+
      |                      tau |           
      |                          |           
      |                   +-------------+   
      |        mu         |             |   
      +------------------>|    Normal   |
                          |             |----+
                          +-------------+    | 
                                     ^       | mu
                                     |       |
                                     +-------+
