From Principles of Data Visualization to Some Really Cool Projects

In this meetup we'll start with the foundations (theory/principles of datavis) and we'll get to some awesome interactive visualizations like http://users.dma.ucla.edu/~mpeteu/media/visualization/oahu-traffic-incidents/ and some other cool projects.

Alex Nano: Information Design 101

I'll demonstrate the key principles of information design, followed by a survey of notable contemporary data visualizations, finishing with a summary of tools and bibliography.

Bio: Alex has decades of experience with software development and physical computing. Most recently, he's been working on applications that test a faster, safer, and more open Internet under the NSF's Future Internet Architecture initiative at UCLA (named-data.net); as well as working on various civic computing projects (remap.ucla.edu). Reducing potentially complex systems into novel intuitive interfaces is the unifying factor behind his work.

Mihai Peteu: Overcoming Barriers to Entry in Contemporary Data Visualization

We’ve come a long way from Jon Snow’s 1854 Broad St Cholera Outbreak map. The datasets nowadays are gigantic: definitely richer, but also more daunting to deal with. A certain degree of technical skill is necessary at every step, along with an affinity for visual design principles. I will share what I have learned while teaching a Data Viz course at UCLA. I will cover the tools used (ffmpeg, D3), obstacles encountered, and the design process that lead to a compelling end product.

Bio: Michigan State Computer Science undergrad, followed by a Master's in Game Design and Film at USC. Currently looking for a way to merge visual storytelling, animation, maps, and data analysis. Open source data is great, but not as fun as data that you scrape.

Timeline:

- 6:00pm food+drinks and networking

- 7:00pm talks start promptly

You will have to arrive between 6:00-6:55pm in order to pass security (see more info below).

Please RSVP as places are limited.

Venue: Cornerstone OnDemand http://www.cornerstoneondemand.com/ will kindly host this meetup and provide food+drinks. There is no parking provided, but at that time of the day it's not difficult to find parking nearby. Please note that only members with RSVP Yes will be able to clear security.

      Thanks Mihai for the work with the videos. (FYI Mihai took the videos previously posted and cleaned them up/edited them a bit.)

    I'm helping to put together the Big Data Track at SCALE 12x on Sun 23rd. I've been thinking that it maybe nice to have a big data visualization using open source tech presentation, IF you know of anyone whom would make a good presenter, please let me know ASAP. Thanks!

      I may have to go out of town that weekend. Is there any chance that a group member could video record the open source data vis presentation?

      February 7

    • Matti S

      fyi - I know the volunteer crew at SCALE 12x will attempt to record the sessions, the challenge we had last year was getting enough volunteer assistance in post production and editing of the video we took.

    Great to see everyone there! Remember we will have a Big Data track with a visualization presentation on Sunday Feb 23 at SCALE 12x. Hope to see everyone join us at SCALE. http://www.socallinuxexpo.org/b...­

      Was there a promo code for us to use when registering for SCALE 12x?

      Code for our group is: VISLA
      Looking forward to seeing everyone there.

    Great meetup!

    During Mihai's talk, the topic of geolocating came up. You can also use the Google Places API to do this (Note: you need an API key from Google). Below is some R code that searches for The Wiltern and returns its coordinates and address.

    library(RCurl)
    options(RCurlOptions = list(cainfo = system.file("CurlSSL", "cacert.pem", package = "RCurl")))
    library(ggmap)
    library(RJSONIO)

    # Plug in the lat\lon of LA
    lat.search <- 34.05
    lon.search <- -118.25
    place <- "The+Wiltern"
    # Your google places API key
    your_key <- ""

    # Search for The Wiltern
    api.call.result <- getURL(paste("https://maps.googleapis.com/maps...;­,
    lat.search,",",lon.searc­h, "&radius=50000&keywor­d=", place,
    "&sensor=true&key="­,your_key, sep=""))

    # Parse the JSON
    parse.result <- fromJSON(api.call.result,simplify = FALSE)
    # Examine the first result from the search
    parse.result$results[[1]]

    Is this going to be live streamed like the last meetup?

    1 · January 21

    • Szilard Pafka

      Our host Tony @Cornerstone said they will try to ustream. I cannot guarantee that it will work, but we'll try. Link will be posted here.
