The Beautiful Hidden Logic of Cities

Padrões identificados em mapas de cidades.

After finishing my map of the most common road suffixes by length, I realized I could also map each individual road, colored by its suffix. This has led to the loveliest maps I’ve made.

Driving around your city, you’re probably somewhat aware of Avenues and Boulevards and Streets and Roads and so on. Here in Portland, at least, I know that Avenues run north-south and Streets run east-west. However, it’s hard to get an overall view of how all these road designations knit together. By coloring them, we can suddenly see a new, stunning view of what we normally take for granted.

Making of the Illustrations of the Natural Orders of Plants

If someone told me when I was young that I would spend three months of my time tracing nineteenth century botanical illustrations and enjoy it, I would have scoffed, but that’s what I did to reproduce Elizabeth Twining’s Illustrations of the Natural Orders of Plants and I loved every minute.

After the unexpected successes of my Byrne’s Euclid and Werner’s Nomenclature of Colours projects (for which I’m very grateful) I got the itch to follow them up with another reproduction of an obscure catalog from the 1800s. However, finding interesting obscure catalogs want an easy task when I didn’t know what would pique my interest. Anything was fair game but I had an inkling that something based on the sciences would be most interesting. Scientific catalogs are organized, structured, and data can be extracted from them with some elbow grease.

Wrapping your brain around data online can be challenging, especially when dealing with huge volumes of information.

And trying to find related content can also be difficult, depending on what data you’re looking for.

But data visualizations can make all of that much easier, allowing you to see the concepts that you’re learning about in a more interesting, and often more useful manner.

Below are 50 of the best data visualizations and tools for creating your own visualizations out there, covering everything from Digg activity to network connectivity to what’s currently happening on Twitter.

Ontologies versus Data Models

By Malcolm Chisholm
AUG 12, 2014 5:00am ET

Data models have been with us since Ted Codd described normalization in 1970 and Peter Chen published his paper on entity relationship diagrams in 1976. Ontology as a discipline in philosophy can trace its roots to ancient Greece. As applied to data management, it is much more recent than data modeling and has only appeared in the past few years. But just what is the difference between ontologies and data models? If they are both about data, do they not boil down to the same thing?

Century of rock history

Para quem gosta de música esta visualização é extraordinária

Para quem gosta de música esta visualização é extraordinária

Jessica Edmondson visualized the history of rock music, from foundations in the pre-1900s to a boom in the 1960s and finally to what we have now. Nodes represent music styles, and edges represent musical connections. There are a lot of them and as a whole it’s a screen of spaghetti, but it’s animated, which is key. It starts at the beginning and develops over time, so you know where to go and what to look at. Music samples for each genre is also a nice touch. [Thanks, Jessica]

Brainstorm, ou ainda Brainstorming, significa literalmente “tempestade de ideias”. No Brasil, por vezes é jocosamente denominado “toró de parpites”. É uma técnica criativa para obter ideias e soluções. De tão simples que é, muitas vezes é aplicada de forma inadequada, simplesmente como se fosse um bate-papo. Iremos ver aqui no Blogtek algumas técnicas para a busca de soluções de problemas.

Brainstorm – definição e aplicações

Data Science is the competitive advantage of the future for organizations interested in turning their data into a product through analytics. Industries from health, to national security, to finance, to energy can be improved by creating better data analytics through Data Science. The winners and the losers in the emerging data economy are going to be determined by their Data Science teams.

Booz Allen Hamilton created The Field Guide to Data Science to help organizations of all types and missions understand how to make use of data as a resource. The text spells out what Data Science is and why it matters to organizations as well as how to create Data Science teams. Along the way, our team of experts provides field-tested approaches, personal tips and tricks, and real-life case studies. Senior leaders will walk away with a deeper understanding of the concepts at the heart of Data Science. Practitioners will add to their toolboxes.
