Subject: Use local variables for storing visualizer dicts.
X-Git-Tag: final-thesis~281
X-Git-Url: https://git.stderr.nl/gitweb?a=commitdiff_plain;h=1687b8573daf7ee73241fa2651ac5bed07c10cdf;p=matthijs%2Fmaster-project%2Freport.git

Use local variables for storing visualizer dicts.

Using global variables could cause problems when pretty printers call
eachother and use the vis variable.
