Small Team, Big Value: Using R to Design Visualizations

Transcript

1. Small Team, Big Value 
 Using R to Design Visualizations Ian Lyttle, Schneider Electric @ijlyttle
2. Who are Schneider Electric? • We are more than 150,000 employees worldwide. • We help our customers use electricity safely and efficiently.
3. How do we use data? Our products collect and transmit data on things like: - power consumption - number of operations - room temperature Our customers have questions like: - “When will I need to replace the power-supply battery?” - “Did my facility use too much energy last month?” - “Do I have enough cooling in my data-center?”
4. SE Customer-Facing Tools
5. SE businesses use different visualization toolsets, including: Each runs in the browser and uses JavaScript. None of these is ggplot2. SE Customer-Facing Tools
6. SE businesses each have data-science teams. SE also has a central data-science team. This is who I work with. Import Tidy Transform Visualize Model Communicate Wickham & Grolemund,
 R for Data Science How are we organized?
7. How are we organized? Import Tidy Transform Visualize Model Communicate Wickham & Grolemund,
 R for Data Science Import, Tidy, Transform, Model -Larger team, based in France -Uses Python
 -Deploy models and data as web services

11. • Solid advice • Uses ggplot2 • No code in book Claus Wilke Technique https://serialmentor.com/dataviz/
12. Jenny Bryan Tooling https://twitter.com/JennyBryan/status/878016566826225664 • Focus on what’s important. • Work towards good-enough. • Workflow to support this: • {usethis} package • https://happygitwithr.com • https://rstats.wtf

15. SE Categorical Palette SE brand colors optimized for marketing: Not optimized for data-visualization. • Propose a related categorical-palette • Take into account color-vision deficiency • Remain “Schneidery” Challenge
16. SE Categorical Palette SE brand colors optimized for marketing: Not optimized for data-visualization. • Propose a related categorical-palette • Take into account color-vision deficiency • Remain “Schneidery” Challenge Technique • Book offers useful advice • {colorspace} package • Achim Zeileis @ UseR! 2019 • Think in terms of hue, chroma, luminance
17. Hue Chroma Luminance Color-vision deficiency Perceptual distance Visible Gamut RGB Color space Just-noticeable difference CIEDE-2000 “Crayola bright”

19. SE Categorical Palette SE brand colors optimized for marketing: Not optimized for color-vision deficiency. • Propose a new palette • Take into account color-vision deficiency • Remain “Schneidery” Challenge Technique • Book offers some advice • {colorspace} package • Achim Zeileis @ UseR! 2019 • Think in terms of hue, chroma, luminance
20. SE Categorical Palette Technique • Book offers some advice • {colorspace} package • Achim Zeileis @ UseR! 2019 • Think in terms of hue, chroma, luminance • Need numbers to show
 perceptual-differences • {farver} package • {paleval} ijlyttle/paleval: • Built on {colorspace} and {farver} • Good enough for now, improve later Tooling
21. SE Categorical Palette • Need numbers to show
 perceptual-differences • {farver} package • {paleval} ijlyttle/paleval: • Built on {colorspace} and {farver} • Good enough for now, improve later Tooling • Created internal blog • {distill} via GitHub Enterprise Communication
22. SE Categorical Palette • Seek more opinions,
 new perspectives • Community@Work, Data Visualization: • By practitioners for practitioners • Point-of-contact with SE UI Design Team Community • Created internal blog • {distill} via GitHub Enterprise Communication
23. SE Categorical Palette Proposed categorical palette: • Takes into account color-vision deficiency. • Potentially “Schneidery”. • Useful feedback: may remove reds. Designed using R, delivered as hex-codes. Result
