We will show how VisTrails can be used to streamline data\nexploration and visualization. Using real examples, we will demonstrate key\nfeatures of the system, including the ability to visually create information\nprocessing pipelines that combine multiple tools and Iibraries such as VTK,\npylab, and matplotlib. We will also show how VisTrails leverages provenance\ninformation not only to support result reproducibility, but also to simplify\nthe creation and refinement of pipelines.\n\n", "quality_notes": "", "copyright_text": "Creative Commons Attribution-NonCommercial-ShareAlike 3.0", "embed": "", "thumbnail_url": "", "duration": null, "video_ogv_length": 159842063, "video_ogv_url": "", "video_ogv_download_only": false, "video_mp4_length": null, "video_mp4_url": "", "video_mp4_download_only": false, "video_webm_length": null, "video_webm_url": "", "video_webm_download_only": false, "video_flv_length": null, "video_flv_url": null, "video_flv_download_only": false, "source_url": "", "whiteboard": "", "recorded": "2010-02-19", "added": "2012-02-23T04:20:00", "updated": "2014-04-08T20:28:28.230" }
