This gist shows how to create a GIF screencast using only free OS X tools: QuickTime, ffmpeg, and gifsicle.
To capture the video (filesize: 19MB), using the free "QuickTime Player" application:
| class BaseChart | |
| constructor: -> | |
| @_width = 720 | |
| @_height = 80 | |
| draw: (selection) => | |
| me = @ | |
| selection.each( (d, i) -> me._draw(this, d, i) ) |
| class BaseChart | |
| accessors: | |
| width: 100 | |
| height: 100 | |
| _margin: {} | |
| @margin: top: 0, right: 0, bottom: 0, left: 0 | |
