Cartographer Zachary Forest Johnson has presented a novel way of representing a large number of geo-located points on a map. He took inspiration from the original 'hexbin' visualization method, short for hexagonal binning (PDF!), which originally is meant to aggregate scatterplotted points into an hexagonal grid, of which each cell is then colored or sized according to a specific value (e.g. relative density or average numerical value) of those points that fall within it. This method avoids the need to render thousands of, potentially overlapping, points (e.g. see NYTimes Maps U.S.
a large-scale data visualization of the textual analysis of English translations of the Holy Scriptures, illustrating the relationships between Christianity, Islam, Hinduism, Buddhism & Judaism. in Similar Diversity, all characters are aligned alphabetically on the x-axis. their name & arc size is calculated from their total word count in all scriptures. the colored arc segments show the frequency of the word or the character in the particular Holy Books. bar charts below the names break down the activities of the characters in detail. the arcs connecting the names symbolize similarities of the activities assigned to a character pair.

إِنَّ الَّذِينَ آمَنُوا وَعَمِلُوا الصَّالِحَاتِ سَيَجْعَلُ لَهُمُ الرَّحْمَـٰنُ وُدًّا ﴿ ٩٦ ﴾ فَإِنَّمَا يَسَّرْنَاهُ بِلِسَانِكَ لِتُبَشِّرَ بِهِ الْمُتَّقِينَ وَتُنذِرَ بِهِ قَوْمًا لُّدًّا ﴿ ٩٧ ﴾ وَكَمْ أَهْلَكْنَا قَبْلَهُم مِّن قَرْنٍ هَلْ تُحِسُّ مِنْهُم مِّنْ أَحَدٍ أَوْ تَسْمَعُ لَهُمْ رِكْزًا ﴿ ٩٨ ﴾ بِسْمِ اللَّـهِ الرَّحْمَـٰنِ الرَّحِيمِ
Important Tools for Visualising and Communicating Data This list of resources represent an ongoing and growing series of blog posts presenting the most inspiring collection of important, effective, useful and practical data visualisation tools.
At the end of each month I pull together a collection of links to some of the most relevant, interesting or thought-provoking articles I’ve come across during the previous month. If you follow me on Twitter and Google+ you will see many of these items shared as soon as I find them. Here’s the latest collection from a very busy September 2011: DataMarket Blog | DataMarket’s chart types – different ways to look at data DataMarket Blog | Data Visualization – Where normal people fall in love with data
Series editors: Clare Birchall (University of Kent), Gary Hall (Coventry University), Joanna Zylinska (Goldsmiths, University of London) Funded by the Joint Information Systems Committee (JISC), and published by Open Humanities Press (OHP) (http://openhumanitiespress.org), Living Books About Life is a series of curated, open access books about life -- with life understood both philosophically and biologically -- which provide a bridge between the humanities and the sciences. Produced by a globally-distributed network of writers and editors, the books in the series repackage existing open access science research by clustering it around selected topics whose unifying theme is life: e.g., air, agriculture, bioethics, cosmetic surgery, electronic waste, energy, neurology and pharmacology. By creating twenty one ‘living books about life’ in just seven months, the series represents an exciting new model for publishing, in a sustainable, low-cost manner, many more such books in the future.

Starting in 2008, Jeff Hammerbacher ( @hackingdata ) and I sat down to share our experiences building the data and analytics groups at Facebook and LinkedIn . In many ways, that meeting was the start of data science as a distinct professional specialization (see the “What makes a data scientist” section of this report for the story on how we came up with the title “Data Scientist”). Since then, data science has taken on a life of its own. The hugely positive response to “ What Is Data Science?
As themes for conferences go, Points of Control is one of our favorites. Our industry over the past year has been driven by increasingly direct conflicts between its major players: Apple has emerged as a major force in mobile and advertising platforms; Google is fighting off Microsoft in search, Apple in mobile and Facebook in social; and Facebook itself finds itself on the defensive against Twitter and scores of location startups like Foursquare. Nor are the Internet’s biggest players the only ones in the game – the rise of tablet computing has revived nearly every major hardware and handset manufacturer, and the inevitable march of online payment and commerce has roused the financial services giants as well.
The question is often asked “What is a map?” Out here on the Edge, the question might just as well be asked “What is not a map?” Before getting involved in that, let me propose the metaphor of the Map Family Picnic.
To swap between Roman and Arabic mode in this text box, hit ctl-' (that's control and apostrophe). The box will shade blue when it's in Arabic mode. From there, type Roman letters that look like the Arabic ones you want. Play around with it and you'll probably figure it out.
Using Hadoop for analytics and data processing requires loading data into clusters and processing it in conjunction with other data that often resides in production databases across the enterprise. Loading bulk data into Hadoop from production systems or accessing it from map reduce applications running on large clusters can be a challenging task. Users must consider details like ensuring consistency of data, the consumption of production system resources, data preparation for provisioning downstream pipeline. Transferring data using scripts is inefficient and time consuming.
This is the seventh part of a multi-part series designed to share with readers an inspiring collection of the most important, effective, useful and practical data visualisation resources. The series will cover visualisation tools, resources for sourcing and handling data, online learning tutorials, visualisation blogs, visualisation books and academic papers. Your feedback is most welcome to help capture any additions or revisions so that this collection can live up to its claim as the essential list of resources. This seventh part, alongside part eight and part nine , presents a comprehensive collection of the books that have had most influence on my knowledge about data visualisation and its many closely-related subject areas. The selection presented includes only the books I own or I have read from a library – I have decided to exclude any books I’ve not yet read, even if they might be on other reading lists.
