A compiler infrastructure for data visualization


There are many data visualization tools out there. Yet, I believe we're still lacking a robust, scalable, and cross-platform visualization toolkit that can handle today's massive datasets.

Most existing tools target simple plots with a few hundreds or thousands of points: bar plots, scatter plots, histograms and the like. Typically, these figures represent aggregated statistical quantities. Maps are also particularly popular, and there are now really great open source tools.

Perhaps contrary to a common belief, this is not the end of the story. There are much more complex visualization needs in academia and industry, and I've always been unsatisfied by the tools at our disposal.

Big Data visualization with WebGL, part 2: VisPy


In this post series, I'm describing the big data visualization platform I'm currently developing with WebGL. I'll detail in this second post the VisPy library which is the basis of the project.

Big Data visualization with WebGL, part 1: Overview


In this post series, I'll talk about the big data visualization platform I'm currently developing with WebGL. I'll give in this first post the main motivations for this project. The next posts will contain the technical details.

Back from our first Vispy code camp at ESRF


We had our first official Vispy Code Camp this week. I and the other core developers of Vispy were kindly invited by the European Synchrotron Radiation Facility. We presented our young library to software engineers from the ESRF and other European synchrotron facilities. It was also the occasion for us to make a gentle introduction to modern OpenGL, as many attendees didn't have experience in real-time GPU rendering. We discovered various scientific use cases in need of high-bandwidth, low-latency real-time visualization of big data.

Hardware-accelerated interactive data visualization in Python


There have been several interesting discussions recently about the future of visualization in Python. Jake Vanderplas wrote a detailled post about the current state-of-the-art of visualization software in Python. Michael Droettboom, one of the Matplotlib's core developers, consequently wrote about the future challenges Matplotlib will need to tackle. Matplotlib has been designed more than ten years ago, and now needs to embrace modern trends including web frontends, high-level R-style plotting interfaces, hardware-accelerated visualization, etc.
