Tableau Public, Visualisation Dashboard

Via readwriteweb a top notch blog about web tech, I read about Tableau Public Software Which provide you with free* interactive graphs, maps and dashboards for the web.

This video example about taking public data about graffiti in New York, graphing it, mapping it, finding trends in the data and then showing those trends on the Dashboard. If only we had access to this kind of data in Ireland.

The free service which you download to you desktop gives you 100,000 rows of data, or 50mb which you can upload to its site to view and share.

This is the new manyeyes for me, particularly because it can do maps of Ireland and you can upload and manipulated large tables of data at once.

Im not sure of its geocoding will be useful for Ireland but can use the updgraded batchgeocode.com to get the lat lng and input them directly. Batchgeocode now specifically geocodes for and within Ireland.

You can use excel or csv files. You can make a graph, from one sheet a map from another, then put them together on dashboard, making the filters for them global to get a fuller nuanced picture.

I've tried a few here myself using the data from my TD's Exhibit. It nearly makes it my use of Exhibit defunct. It seems like it had more ways to total, average and display data automatically.

Data at TD google spreadsheet
Constituency editable spreadsheet.
Party editable spreadsheet.

Download these files as xls, strip the { and } from the headers and think of ways of displaying the data.

Need to think of ways to use data to fully utilize this. Figure out how to make the difference in size of icons logarithmic.
