Ian Heath, one of the earliest employees at Tableau and a famous Lego artist
1) Ian showed a Kiva demo.  Kiva is a micro-finance lender operating worldwide.  The demo is based on Hadoop data.
    a. Improved tooltips
        i. Keep/Remove items and View Data features appear on tooltips
        ii. Tooltip default text is much easier to read
    b. Dual-axis maps allow the use of multiple mark types on the same locations
    c. Tableau maps now use map cutouts that fill in the entire state
        i. The map shapes can also be used in other view types such as text tables

2) More geocoding and mapping enhancements including a demo of dirty data about the 75 best restaurants in the world
    a. In this data, Britain is no longer “Great”, instead it was in the data as "Britain".  This was one of many mis-spellings.
    b. Geocoding in Tableau 7 adds synonyms for place names and pattern matching so that the best match is often selected without user intervention.

Geocoding dialog is now much smarter and more powerful!

    c. Tableau automatically places almost all items on map despite poor spelling and even foreign spelling of places.
    d. Unknown places are no longer placed at the 0 latitude / 0 longitude location. Instead, a simple message appears in the bottom right of the map specifying how many places are unknown. When you click this message, you have the option to fix these items.
    e. While geocoding, you can add custom latitude and longitude while correcting unknown locations. This is very useful for locations not in the geocoding database.
    e. You can now scroll the world map to center on the Pacific Ocean or anywhere else in the world. The map scrolls continuously instead of ending at the Internation Date Line.
    f. A new feature has been added to automatically center the map based on geographic center of your data.

Analytic features for time analysis.  Demonstrated with 50 M records for US airlines on time status and flight cancellations.

Additionally, the next view, an area chart uncovers additional insights

2) How people spend their daily hours
    a. Area charts now added to Tableau 7
    b. Small multiples area chart was demonstrated

In this area chart,
you can see a significant, persistent decline
in overall flight volume post 9/11

3) Better visual appearance of missing values in time based data
    a. You can now enhance discrete date views like a bar chart to properly space out for sparse data by day
    b. Easily show missing data by day, month, week, day of week, year

4) Parameters available for use in even more dialogs.  Now available in almost every relevant dialog such as bins

Jun Kim- Customer since Tableau version 1.0 and previously at Microsoft Xbox
Now works in User Experience at Tableau
1) Show Me enhancements
    a. Show Me remains open by default so you can quickly change views and
    b. Informs you how to select the needed data items to build a desired view
    c. Bar charts now default to horizontal

2) Specify from a selector in the view how many top or bottom items to display using parameters
    a. Easily pick top 10/15/20 with a slider control

3) Dashboard enhancements
    a. New Dashboard is now a top-level menu item
    b. Adding or moving items in the dashboard clearly show how much space they will take and where they will drop on dashboard
    c. Easily resize elements including an automatic snap to align sizes with other elements

4) Jun wrapped up with a story about a game developer colleague from Microsoft that spent their free time analyzing data instead of playing video games. If a tool is so compelling that people would rather use it instead of playing video games, how much ROI will you have with this type of tool?
James Baker
1) Expanded interaction capabilities when using dashboards from Tableau Server
    a. Moved operations to tooltips such as Keep/Remove items
2) By improving interactivity there is now a much shorter Server toolbar at the top of your content, with half of the items removed and now available close to their logical location of use.

    b. Finger-friendly controls
    c. A single-press will bring up the tooltip for the location of interest

Jeff Solomon
New Tableau Data Server and other data support
1) Added support for Hadoop and SAS
2) Data permissions control and embed credentials now available for server-based data sources
3) You can locally override settings from server data sources in your workbook
4) When a server-based data source is updated, you don't need to close the workbook to see the new definitions. Simply refresh the data to use changes!
5) A new feature has been added to replace any data source with any other data source!  (e.g.- from Excel to SQL Server or from a test database to a production database.)
6) One more advantage of the new Data Server is that no local PC data drivers are required for multiple databases such as Oracle, SQL Server and others.
