Project description

This project visualized a dataset about how scientists migrate from country to country. As literal translation, the title of the project is “Scientists are not only ‘geeks’, but like leading a wandering life around the world.” And the small illustration shows three common statuses of scientists: Students, Researchers, and Professors.It was published on March 16, right before the “Chinese National Scientific Talent Day”, it is in memory of March 18, 1978, when “Science and Technology are productivity”. From then on, scientists and technicians have the opportunity to go abroad, exchange with the world, bring back more advanced technology.We explored the data of 300 million scientists’ CV around the world and visualized it in a new way.Among the dataset, we picked a scientist, who has been to 11 countries for his research and education. Also we interviewed him in detail how he felt about the ‘journey’ life. An animation path on world map was made especially for his journey. And then, we visualized the data on map. The dataset is very big, so we help readers explore the data from three dimensions. Colors on countries show the percentage of each country exports or imports scientists to other places. At the mean time the yellow path represents scientists migrations between any two countries, with color/width shows the data differences. The updated table on the left side highlights the top ten countries export or import scientists from or to the country which readers are hovering. To make the data more direct to understand, we assume there are 100 thousand flowing scientists, then the number of the scientists would be automatic calculated according to the percentage.The third chart focuses on where scientists working in China and the States come from, and where the phD graduates enter after achieving the degree from the two countries.

What makes this project innovative?

The interactive map uses map, arc, and voronoi.js together. It is difficult to hover on map with such a dense arcs on. Voronoi.js helps solve the problem pretty well. No matter where readers hover around the map, a nearest place can be sensed exactly. The second thing is that the mobile version for the interactive part shows in another way. We picked out ten countries with a large amount of scientists migration to show the data. It solved the problem that a horizontal world map cannot show arcs decently on mobile. It highlighted important points and attacked readers to the PC version.

What was the impact of your project? How did you measure it?

The flow of talents is a major issue for countries and the whole world. This project shows the situation in details. Many readers told us they begin to think about it after they read this. Normally “Scientific Talent Day” is not a famous festival. This project brings the anniversary back to people’s sight.

Source and methodology

We got the dataset from Tiny Letter’s dataset push. The datadryad opened ORCID’s 2.8 million public profiles in json format. Luckily the Python code to analyze the dataset was also open to public and we used python to do the analysis based on it.

Technologies Used

Python is used for data analysis and statistics.Adobe illustrator, Adobe Effects and Adobe Animation are used for graphs and animation.HTML, CSS, JavaScript (d3.js and voronoi.js spectacular) are used for web page and data interactive visualization.
