MIniature Wood Houses by Daniel Barreto

Artist on Tumblr

We’re loving these clever and subtle gif images created by 21 year old Boston, MA based illustrator Daniel Barreto. The small dwellings are carved into the nooks and crannies of trees deep in the woods. Their windows glowing with light and flickering in the dark snowy night beg the question “who built this house and how do they exactly live here. ”

SHARKS HAVE INCREDIBLE HEALING ABILITIES

Wound healing is important for sharks from the earliest life stages, for example, as the ‘umbilical scar’ in viviparous species heals, and throughout adulthood, when sharks can incur a range of external injuries from natural and anthropogenic sources.

Recently, researchers documented the rapid healing of the Blacktip reef sharks (Carcharhinus melanopterus) following an internal tagging procedure involving a small incision in the belly of the shark to implant the transmitter. This not only shows that sharks are healing quickly but also that they are robust to this tagging procedure which is important to know as a scientist when you work with free-living animal.

Small umbilical wounds in neonates decreased in surface area by 71% in less than a week and were barely detectable after 24 days.

Also in the study were reported two cases of survival after fin removal due to targeted shark-finning in which the basal wound of fin removal healed well and the sharks were observed alive a while after injury, swimming without their dorsal fin. However, even if they survive for un unknown time, the removal of the dorsal fin may greatly affect their daily life and in turn their fitness (and most of finned sharks may not survive).

Sharks, and probably rays too may be resilient to injuries, showing rapid healing from minor wounds and long-term survival from even major mechanical injuries. These are positive findings for elasmobranch conservation, especially considering that up to a quarter of all shark and ray species worldwide are threatened with extinction. 

Despite this incredible ability, researchers encourage minimal handling time and stress when releasing sharks after fishing or by-catch, which could include cutting a line near the hook instead of repeatedly attempting to remove the hook. Anglers should also be made aware that sharks can recover from mechanical injury; therefore, sharks should be released even if the animal sustains injuries during the capture process.

Easy network graphs for Tableau with NodeXL

Download Node XL

Enter some edges, add additional measures and/or dimensions

Click “Workbook Columns” -> tick “Layout”

Choose your graph type and layout

Click “automate”

Delete row 1 in both Edges and Vertices.  Save Edges and Vertices as CSV.

Create a new Excel workbook and import Edges and Vertices as two new sheets.

In “Edges” create 4 new columns: Vertex1x, Vertex1y, Vertex2x, Vertex2y. Perform a VLOOKUP Vertex 1 from “Edges” against Vertex in “Vertices” to populate the x and y and then do Vertex 2.  

Select cells in “Edges” (CTRL-A) and Paste special -> values only. We can then delete “Vertices”. 

Copy “Edges” to another sheet.  Rename Edges “From” and the copy “To”.  Add a column in both called “pathorder”.  “From” will be populated with “1″ and “To” will be populated with “2″.

Then open Tableau, choose Excel, open with legacy connection. 

Choose custom SQL and enter the query:

SELECT *, Vertex1x AS [X], Vertex1y AS [Y] FROM [From$] UNION ALL SELECT *, Vertex2x AS [X], Vertex2y AS [Y] FROM [To$]

Then in Tableau, build a dual axis, line mark type for edges, and circle for vertices.  Change ID, pathorder, X and Y to dimensions.

You should now have a network graph in Tableau.

Note, I haven’t gone in depth about the mathematics here.  It’s just a simple example.  Also, you maybe thinking, what if I have more than 500,000 rows.  Well, just append your CSVs into Postgre SQL and do the union there.  Or maybe you want to generate a VBA Macro to automate this process? If you do, you can always contribute your script to a github for Tableau.

Tableau 9.0 beta 

Tableau 9.0 beta has been released, and Tableau Public has shaped up to be real eye candy.  The UI in both desktop and Tableau Public have been given an overhaul, and there is a lot to like.  Regular expressions, random function, in pill editing, and the mapping gets a lot more power: in-map entity search, lasso/marquee select - although my favorite new capability (although the Apple Mac users have had it a while) - a color picker! With RGB and hex values!

Network graphs

I’ve been quietly sitting on the two data sets above, trying to make sense of the underlying fields; for example, with the maxmind dataset, I had to work out how to parse an interger as an octlet; i.e. 1.0.0.1 - and then using split_part in Postgre SQL (no CHARINDEX function available) to get rid of the end of block. The workbook has two inner joins and a union (Maxmind), and a second data source in MS Excel.

Why bother though?  Well, I’m fascinated by flow. Whether that is people, aircraft, money, or ip packets. Of course we can animate these graphs over time - but really, what are we looking for; what is the story?

Well I’ll tell you what I think know from experience what decision makers are looking for.  They are looking for anomalies. They want to know what are the biggest fluctuations, usually in the fattest “pipes”.  Flat lines and small pipes (think opportunities) are typically just noise.  For those building bar and pie charts into pretty looking dashboards, this is going to come as news and a bit of a shock.

Graph edges (vertices) can be encoded in size by metric - and once you build the matrix (array) you can also compute cost (distance is a normal consideration, time, bandwidth etc).  This can also be represented as a Sankey, but if there is a geo-spatial component to the data, then a map helps us interpret the data quicker.  As cave dwellers, we didn’t make bar or pie charts to tally up the hunt/gender ratios, we drew a map in the sands of how to get to the killing fields.

My Missions

I am going to continue pushing the integration of Business and Geo-spatial Intelligence.  I continue to champion Tableau, and I’m starting to integrate not just with ESRI, Mapbox, Geoserver etc but also with other XML/JSON based APIs, javascript libraries such as Cesium, d3, & three.js.

This is to support the next mission though - full sensory data exploration.   I’ll go further in depth at a later date; explain though some technologies, where I’ve got too so far, and why.

An Interactive Map for Baton Rouge Restaurant Week

Restaurant week

Mapping Month

As a resident of Baton Rouge for a few years and a proud South Louisiana Cajun since birth, most traditions and memories I hold dearly revolve around delicious meals. Whether it was a graduation celebration or a football tailgate, “what’s on the menu?” was always a hot topic. The excitement I’d feel around Restaurant Week was close to that of opening presents on Christmas morning. As an LSU student, a three-course meal for only $15 was a steal, and a great excuse for an impromptu girls’ night out. After graduation, it gave me the opportunity to visit new locations, sip on local brews and discover favorite dishes!

As a recent transplant to Oklahoma, and as I travel around the country evangelizing Tableau, I find myself missing boudin balls, jambalaya and Monday-night red beans and rice. So, in honor of Restaurant Week, my Cajun heritage AND Tableau’s Mapping Month, I decided to create an interactive map using Tableau and a custom map from Mapbox that shows all the best restaurants you should check out in Baton Rouge. Though I’m missing home, my one request from all of you is that you treat yourself this week! Find a babysitter for date night, procrastinate a bit more on the homework or grab some friends from work and check out all of the incredible eats your local area has to offer!

6 Tips to Make Your Dashboards More Performant

By Nicholas Hara Jan 15, 2016

We here at Tableau are very proud of how easy it is to see and understand data with Tableau. Once you get started, it’s intuitive to dive deeper by adding more and more fields, formulae, and calculations to a simple visualization—until it becomes slower and slower to render. In a world where two-second response times can lose an audience, performance is crucial. Here are some tips on making your dashboards more performant.

and here we go: all current Flight Rising dragon breeds, all together! I used the average sizes for each breed, which is is as follows (in order from left to right in the second image):

Imperial: 21m

Ridgeback: 18m

Guardian: 15m

Snapper: 5m

Pearlcatcher: 5.65m

Mirror: 5.7m

Wildclaw: 5m

Tundra: 3.48

Skydancer: 5.66

Spiral: 3.25

Fae: 1m

and again, the human silhouette is 1.83m/6’. this was a fun project and I think I can get back to actual arts now, and while I enjoy having this reference, I also still take dragon sizes with a big grain of salt (and don’t even get me started on wingspan & weights ok)!

you can also nab a larger size (2500x1185 pixels) of the second image over here on dA, and you can check out my tag #drag size chart for individual size charts of each breed (with smallest, largest & average).
