DDV - Introduction to ffmpeg and Plotting Large Datasets with D3.js and WebGL

Thanks to Tim Mapley and Chris Dickman for volunteering to speak at our February event!

• 11:00am: Lunch, Sponsors, and Announcements

• 11:30am: ffmpeg Command Line Examples: ffmpeg is a free, open source, and widely used program for converting, streaming, and filtering media. Tim will explain 15+ ffmpeg command line examples with video and audio - mostly geared towards home use. Tim Mapley has an BSEE from Michigan Technological University and has supported NASIC for over 10 years as a developer (C#, Java), system administrator, and DBA.

• 12:00pm: Plotting 100k Data Points with D3.js and WebGL: D3.js is popular and easy to use but we start to see performance issues when exceeding 500 data points. Chris Dickman will share his experience evaluating options for building interactive 2D plots to visualize 100k data points and demonstrate a hybrid D3/Three.js 2D scatter plot. Chris has been building web-based applications in the public and private sector for 15 years. He is currently a Software Engineer at Applied Information Sciences.

• 12:30pm: End

Welcome to the Dayton Data Visualization group! We’re looking for speakers and sponsors, so please email me at bowmanmc@gmail.com if you or your company is interested in either. This will be a lunchtime meetup in Beavercreek at Applied Information Sciences.

The Dayton Data Visualization group will meet quarterly unless I get enough volunteers to make it happen more frequently. Please volunteer to share a topic with the group! What makes a good presentation topic for DDV? Here are some ideas:

• Case Studies - Show us how you made a cool visualization or infographic

• Development Tips - Show us how to use a cool new tool or framework

• Benchmarks - Comparisons between tools or frameworks

• Data Mining - Show us how you mine/retrieve data to use in your visualizations

• Optimization - Show us how you optimize your visualizations for performance on the web and mobile devices

Presentations are only twenty minutes long. This is to lower the barrier of entry for new speakers and to make the talks less of a time commitment from the speakers (and audience). Keep them short, sweet, and specific.

Thanks!
