I recently finished the Data Science Specialization offered by Coursera. It is a nine course sequence that covers all aspects of data science, from finding and cleaning data, to creating reproducible research, applying regression models and machine learning, and producing data products. The final class is called Developing Data Products and we were required to develop a project for it. For my project I created an interactive data visualization of data scientist jobs worldwide that I call “Where The Jobs Are”. The app processes data scientist job listings obtained from the API, showing numbers of jobs and salary ranges in bar charts and box plots by region. Users can drill down one level by selecting the region and see jobs by city. They can also see job listing details and click through to the actual job advertisement.

The app is built with R and Shiny, while the Careerjet API is accessed with a Python script. Here are a couple of screenshots.
