Learning from a Graph

books, writing

Jan 2017

Yasiv is a wonderful tool to browse product data at Amazon. By looking at a graph of sales data, where does our book Node.js for embedded systems stand?

The graph of book sales Amazon can provide some insights:

The graph shows different kinds of products from the Amazon product catalog. The lines between nodes shows how books are combined in a shopping cart.

In the middle, the yellow circle shows the book “Node.js for Embedded Systems”. It connects with a number of different product categories: Raspberry Pi, Arduino, BeagleBone, Robots, Design and Web Development.

Let’s look into details. First, people buy this book together with books on materials on Raspberry Pi and Arduino (cyan circles top left). Single board computers are indeed an interesting start with embedded systems. Books on Beaglebone are also connected to this (see orange circle).

Second, there is a whole book category on Robots (red circle). From the data, it looks like robot books are more connected to Raspberry Pi and Arduino, than they are to Beaglebone. It seems our book could add an interesting link here, but it is not yet what people see. Somehow in this direction of machines, books are written on computer architecture and FPGA’s as well.

Third, there is a whole category of books on design of user experiences for connected products. Interestingly, only few books link design with hardware for IoT. Two books are “Wearable Sensors: Fundamentals, Implementation and Applications” (2014) and “Learning Internet of Things” (2015).

Last, there is a large category of books on writing web applications with Node.js or JavaScript in general (blue circles bottom). This is the good news for “Node.js for Embedded Systems”: It seems to be able to link hardware with web applications.
