D3 for Data Scientists and Enthusiasts

D3, aptly named Data-Driven Documents, is a data driven graphical framework.  Unlike many graphical libraries, D3 takes a data first approach:  this makes it one of the hottest web visualization tools for data scientists at the moment.  This talk will review the key characteristics and components of D3 and detail how a little D3 knowledge can go a long way in impressing your colleagues and clients.  This introductory talk will cover the power and flexibility of D3 with numerous examples.

About the speaker:

Sheamus McGovern is a leading technologist with many years experience building complex software platforms particularly in quantitative finance and business intelligence.   Visualization was a critical requirement in many of these platforms.  Currently he is CTO of Capital Market Exchange, a Boston based financial technology startup that uses innovative predictive models to price bonds and other financial securities.  He holds a CQF in quantitative finance and degrees from Northeastern, Boston University, and Harvard.

    Hi Sheamus,
    I went there and saw the file. However when I click on it I got the message "You don't have permission to do that". What am I doing wrong?

    Re the resource file. As Jane mentioned you may have to go directly to the 'more' menu and then select files.

    Thanks everyone for attending. I should be posting the slides in the next day or two.

    Thank you for a beautiful presentation!
    A few notes ref. discussions,

    1) Dynamic data (d3js.org),
    “D3 lets you transform documents based on data...even asynchronous notification from a third-party.
    A hybrid approach is even possible, where the document is initially rendered on the server, and updated on the client via D3”; 2) Suitability (“Interactive Data Visualization for the Web”, chapter “What it doesn't Do”),
    - “D3 doesn’t even try to support older browsers”;
    - “D3 doesn’t hide your original data... If your data can’t be shared, then don’t use D3.”

      Another advantage/limitation of D3 is that new transitions abort older transitions rather than queuing them like jQuery. That could be very useful or very frustrating depending on what you're doing.

    Regrettably I could not make it. Will the slides/code recording be available? Thank you!

  • Jacob T.

    Great job, Sheamus. Very inspiring graphs. Thank you!

    Timely topic. Sheamus' enthusiasm was contagious. Presentation had some good WOW factors and left everyone feeling that they could just as easily do a similar visualization with existing code and a few line changes. Thank god we do not have to recreate the wheel, since someone has already done that. Just modify an existing one. And thanks to Heather and Basis Technology ( www.basistech.co.jp ) for the food and drink. Now go and use her services.

    Sheamus, you gave a most informative presentation. I personally liked your relaxed style and openess about coding and how you work.
    Thank you.

    Will this talk make reference to code that's available online? i.e. specific examples in the d3 gallery? Someone's github somewhere?
