Effective Visualization (Color) Design

Schedule:

6:30 - 7:00 - hang out, demos

We will have pizza and beer! This meetup is sponsored by OpenVis Conf (http://openvisconf.com/), a 2-day conference about the practice of Data Visualization on the open web. See the lineup on http://OpenVisConf.com (http://openvisconf.com/)! - Be sure to join us in person to get a discount code for meetup attendees.

7:00 - talk start

Abstract:

This talk will cover common limitations for making categorical visualization color palettes, and will also discuss how a new tool, Colorgorical, can help automate the palette design process. By dragging sliders in Colorgorical, users can manipulate color palette discriminability and preference importances, as well as control a variety of other attributes like the number of colors, predefining colors that should always be included, and whether to limit color selection to certain hues. After introducing concepts from color science, the talk will delve into how Colorgorical works under the hood, and also overview how it is able to automatically produce palettes that are as discriminable and typically more preferable than the defaults included in ColorBrewer, Microsoft, and Tableau. Colorgorical is open sourced and available to try out online at http://gramaz.io/colorgorical .
