School without Water, Electricity or Toilets

Sound appealing? Probably not! Unfortunately, this is the sad reality for many children in Sub-Saharan Africa. Even worse, this sad reality is only for those children lucky enough to even attend school. In the world today, there are 58 million out of school children, and 43% of those children will never start attending school.

FFunction, a Montreal-based data visualization studio, and UNESCO Institute for Statistics (UIS) recently launched 2 interactive data visualizations. Both are creative and innovative ways to present information.

  • Out of School Children – Explore how gender, income, and location affect a child’s education
  • Left Behind – View how and why African girls struggle to obtain an education

3 Great Data Science Books You Can Read Now…for free

Just this week, I have become aware of 3 free online books for data science.

Data Visualization with Javascript

If you are looking for a tutorial to teach you how to make wonderful visualizations on the web, look no further. Data Visualization with JavaScript is a free online book for learning data visualization with Javascript. It provides tons of examples and step by step instructions for how to create the graphs, charts, and other visualizations. Here is a quick list of the topics:

  • Graphs
  • D3.js
  • Interactive Charts
  • Geographic Plots
  • Timelines

Frontiers in Massive Datasets

Frontiers in Massive Datasets is a report all about how science, business, communications, national security and others need to learn to handle massive amounts of data. Whether the data has been sitting in a database for years or it is now just screaming into the systems, massive data is now a problem for almost every industry. This report covers many of the topics that need to be addressed when dealing with big data. Here is a very brief overview of the topics:

  • Limitations
  • Sampling
  • Building Models from Massive Data
  • Real-time Algorithms
  • 7 Computational Giants of Massive Data Analysis

Foundations of Data Science

Foundations of Data Science is a draft of textbook written by John Hopcroft and Ravindran Kannan. It is intended to be a text for computer science with an emphasis more on probability and statistics rather than discrete mathematics. The authors argue that knowledge of working with data is a necessary skill for computer scientists of the future. This is clearly the most technical and academic of the 3 books, but if that is your thing, your should really enjoy browsing through this book. Here are some of the topics.

  • High-Dimensional Space
  • Clustering
  • Algorithms for Massive Data Problems
  • Singular Value Decomposition
  • Graphical Models

Accel Partners: Data Visualization and Data Stories

Accel Partners, one of the largest big data investment firms, hosted a panel discussion on Data Visualization and Data Stories.

Hilary Mason, Data Scientist in Residence at Accel, hosts the discussion. Two great visualization experts that come up in the talk are, Fernanda Viégas and Martin Wattenberg.

This Data Tells A Story

There is nothing magical about this data. It is just income data. The magic comes from the excellent visualizations, and the story being told. If you need to make your data come to life, this video is an excellent example.

Tornado Path Visualization

Here is a data visualization of the paths of tornadoes in the US over the past 56 years. The brighter the blue, the more intense the tornado. This is also an excellent example of using opendata. The raw data is available at data.gov.

Please continue to pray for the people in Moore, Oklahoma. If you feel moved to help, The Red Cross and Convoy of Hope are two organizations working in the area.
