Hans Rosling: Religions and babies

Hans Rosling had a question: Do some religions have a higher birth rate than others -- and how does this affect global population growth? Speaking at the TEDxSummit in Doha, Qatar, he graphs data over time and across religions. With his trademark humor and sharp insight, Hans reaches a surprising conclusion on world fertility rates. In Hans Rosling’s hands, data sings. Global trends in health and economics come to vivid life. And the big picture of global development—with some surprisingly good news—snaps into sharp focus. Full bio » The number of children [per family] is not growing any longer in the world. We are still debating peak oil, but we have definitely reached peak child.” (Hans Rosling)

Datavisualization.ch: A Carefully Selected List of Recommended Tools


A Carefully Selected List of Recommended Tools

When I meet with people and talk about our work, I get asked a lot what technology we use to create interactive and dynamic data visualizations. At Interactive Things, we have a set of preferred libraries, applications and services that we use regularly in our work. We will select the most fitting tool for the job depending on the requirements of the project. Sometimes a really simple tool is all you need to create something meaningful. On other occasions, a more multifaceted repertoire is needed. But how does one choose the right thing to use? An endless list of every tool available, does not answer that question and a recommendation from a friend is oftentimes more valuable.
That’s why we have put together a selection of tools that we use the most and that we enjoy working with. We called it selection.datavisualization.ch. It includes libraries for plotting data on maps, frameworks for creating charts, graphs and diagrams and tools to simplify the handling of data. Even if you’re not into programming, you’ll find applications that can be used without writing one single line of code. We will keep this list as a living repository and add / remove things as technology develops. We hope this will help you find the best tool for your next job.
Let me answer the most likely questions right away: No, not everything find its’ way into this list, so you might not find your personal favorite. Yes, some of the libraries mentioned are brand spanking new and may not be ready for production while others already have successors, but they still provide a good service.
