Dr. Andre,

I had a phone conversation with a sales guy, Mark Evans.

He suggested we could "get by" with Tableau Public, which is free.

He described it as a "YouTube" for data visualizations created with Tableau.

Importantly, the Tableau Public site allows us to embed our data visualization onto the actual IBSS website using a piece of javascript code.

Downsides of Tableau Public:

You can’t "save" a visualization except at the instant you publish it – that means you get your visualization right in one session of working with the data, or you do it over.

On the bright side, you can delete things you create/upload.

I did read on Quora that Tableau Public has a limitation on the number of rows.

I don’t know what the limit is, but I can say that our NIR predict dataset does not exceed the cap:

There are 1,271 rows of data in the Tableau Public version of the NIR-predict dataset, as imported by Tableau Public Desktop

That matches the number of rows in the raw data.

There’s good information here:

For future reference on pricing…

Evans’ recommendation is to get one copy of Tableau Desktop Personal.

There is education pricing for that specific product at $750.

$500 of the license is a one time, perpetual use license.

$150 is an annual "maintenance" charge I was told you don’t actually need to get, you’d just stop getting updates for the software.

Next Steps

  1. I’ve asked SREF if they can modify the plone portal to accept the javascript embed that Tableau provides
  2. Once it’s online, it may be helpful to meet up again to have you go over the available visualizations and pick out the ones that potentially offer the most value.

About Tanner Jessel

I am a recent M.S. in Information Science graduate from the University of Tennessee School of Information Science. I was formerly a graduate research assistant funded by DataONE (Data Observation Network for Earth). Prior, I worked for four years as a content lead and biodiversity scientist with the U.S. Geological Survey's Biodiversity Informatics Program. Building on my work experience in biodiversity and environmental informatics, my work with DataONE focused on exploring the nature of scientific collaborations necessary for scientific inquiry. I also conducted research concerning user experience and usability, and assisted in development of member nodes with an emphasis on spatial data and infrastructure. I assisted with research designed to understand sociocultural issues within collaborative research communities. Through August 1, 2014, I was based at the Center for Information and Communication Studies at the University of Tennessee School of Information Science in Knoxville, Tennessee.
