![]() You will also need to rename one of the files ( dotfile.txt), as described in part 3 before using it in OmniGraffle. Instructions for doing this are found on the following pages. In the preprocessor: retrievetags, taglist.Finally, for those people who just want to run the software and forget about the tutorial aspect for now, make sure to change the following objects in the Anthracite files: While you don't need to be a pro with either program to follow the steps outlined, you do need to know your way around both of them. In the discussion that follows, I will assume that you have gone through the basic Anthracite tutorials, and the basic OmniGraffle tutorials. run OmniGraffle to create the actual graph.run Anthracite a second time to create a dot file that contains the necessary information to create the graph.run Anthracite to obtain the list of tags from the website that we wish to graph.The sequence of steps we will go through is as follows: Finally, since the files that will be produced by Anthracite are in a simple text-based format (known as the dot format), a good text editor might come in handy for those people who want to modify these files by hand - TextWrangler is an excellent and powerful text editor, and is available for free. As an alternative to OmniGraffle, the excellent open source program Graphviz may be used, although it is less user-friendly than OmniGraffle. Neither application is free, but both have free trial periods, should you be inclined to check them out. Hence, I have selected a combination of two very nice applications for Mac OS X - Anthracite and OmniGraffle - to produce similar visualizations. While those visualizations were constructed with a rather eclectic mixture of homebrewed code, assorted applications, and a good bit of elbow grease, I decided to put together a tutorial for people who might be interested in this type of visual exploration, but are not inclined to write custom Perl code to do so. ![]() ![]() Several people have asked me how I produced the visualizations that I used in my talk on. ![]()
