1. Bryan Van de Ven bryanv@continuum.io @bryvdv EuroSciPy 2015 Story Time with Bokeh
2. Callback for sophisticated static documents New tools and annotations • lasso, poly, and point selections • crosshair inspector • hover tool for lines • h/v spans Improved visual design Docs! • 100% complete reference guide • all new expanded user guide RBokeh Prologue
3. Present Day
4. Today Setting the Stage
5. Today Setting the Stage
6. Today Makes the Dream Work Damian Luke Bryan Sara Fabio Mateusz Havoc Almar Peter Nick Kevin Maggie Sarah
7. Static Documents, Dynamic Interaction Today http://nbviewer.ipython.org/github/bokeh/bokeh-notebooks/blob/master/tutorial/00 - intro.ipynb#Interaction
8. Static Documents, Dynamic Interaction Today JS Callbacks extend capability now, for a marginal cost (a few lines of JS) Will encapsulate common patterns as they are discovered (no more JS!) A dream: write callbacks in Python, translate automatically See the new User’s Guide for much more info: http://bokeh.pydata.org/en/latest/docs/user_guide/interaction.html
9. Spectrogram Remixed https://www.youtube.com/watch?v=L6p7Cd3uDis Today
10. Spectrogram Remixed Completely customizable visual styling and templating Performance enhancements (smoother and faster updates) Mostly written in python (previously lots of frontend Javascript) Today
11. Fraud and falsehood… https://www.youtube.com/watch?v=0qGSmDeEQ6Y Today
12. …only dread examination • Identify fraudulent market manipulation activity from a variety of potential sources on the web (Twitter, Facebook, SPAM, forum posts). • Correlate that against "legitimate" market activity, SEC Filings, News and Press Releases, and other market activity. FEAT (Financial Event Analysis Tool) is being evaluated by us.gov in order to Uses only out-of the box features of Bokeh 0.9.3 Today
13. Oceans in the Cloud Today
14. Oceans in the Cloud Today (Small) code you can actually run today Still too much JS (but working on it) Tornado(+Dask) server written in 15 minutes Uses recent AjaxDataSource
15. Speaking of Dask Today Generates .dot file for execution graphs Data was converted to Bokeh glyphs Will enable “live monitoring” for Dask http://dask.pydata.org/en/latest/
16. • LaTeX annotations (KaTeX) • SVG output (MPL or Cairo backend) • New Charts / Faceting (in progress) • Validation (started in 0.9.1) To be continued…
17. Tomorrow Bokeh Authoring https://www.youtube.com/watch?v=VOAXC7XUCto
18. Tomorrow Bokeh Theming
19. Tomorrow Bokeh Server-ing Simplify and narrow the focus of the Bokeh Server (less is more) Extensible facility for reflective, persistent RPC Only pay in size for features you use (shrink BokehJS) Create custom models and widgets (a platform for anyone to extend)
20. • R (Trelliscope), Scala, JS (Angular, React) • WebGL backend (underway) • 1.0 • LaTeX annotations (KaTeX) • SVG output (MPL or Cairo backend) • New Charts / Faceting (in progress) • Validation (started in 0.9.1) • Bokeh App Authoring, Theming • Server revamp, Extensibility To be continued…
 (continued)
21. Call to Action Install Bokeh and provide feedback • BSD license for everything (JS, Python, server) • https://github.com/Bokeh/bokeh Engage us to work on custom apps and dashboards • Code integration, analytical and visualization expertise • Feedback helps the open source efforts
