I’m working on some visualizations and I want to achieve the look of Last.fm visualization lastgraph3<\/a>:<\/p>\n

\"wavegraph\"<\/p>\n

The great thing about this is that Andew Godwin, author of the site open sourced the underlying library – Graphication<\/a>.<\/p>\n

Since I’m an OS X user, I decided to make the whole thing work on my system – Leopard 10.5.6 at the time of this writing. Here are the notes, mostly for my reference and because it might be also useful to others:<\/p>\n

Get free XCode from Apple: http:\/\/developer.apple.com\/<\/a><\/p>\n

First build and install pkg-config from: http:\/\/pkgconfig.freedesktop.org\/releases\/pkg-config-0.23.tar.gz<\/a><\/p>\n

Then install libpng and libjpeg libraries: http:\/\/ethan.tira-thompson.com\/Mac%20OS%20X%20Ports.html<\/a><\/p>\n

Build and install pixman from: http:\/\/www.cairographics.org\/releases\/<\/a><\/p>\n

Build and install cairo from: http:\/\/cairographics.org\/releases\/<\/a><\/p>\n

Build and install pycairo from: http:\/\/cairographics.org\/releases\/<\/a><\/p>\n

Patching:
\n– you’ll need to edit cairo\/Makefile.in file by modifying parameter _cairo_la_LDFLAGS (around line 215) to remove ‘-export-symbols-regex init_cairo’
\n(thanks Michael Dales<\/a>)<\/p>\n

Build instructions:
\n– just follow INSTALL file. Essential running:
\n.\/configure –prefix=\/System\/Library\/Frameworks\/Python.framework\/Versions\/2.5 (sys.path for my system)
\nand then make && sudo make install<\/p>\n

Now you can finally build and install Graphication package \ud83d\ude42<\/p><\/blockquote>\n

All the installations steps are just .\/configure && make && sudo make install and just work out of the box. I already have Python PIL installed from sources and I think you need this for one of the steps, but I’m not sure anymore for which one.<\/p>\n

After you go through all the steps, you can start drawing something like that:<\/p>\n

\"Simple
Simple visualization<\/figcaption><\/figure>\n

Now to figure out how to create something meaningful with it.<\/em><\/p>\n
