Some weeks ago, I had the opportunity to attend the D3.js learning workshop in Tampere, arranged by Open Knowledge Finland, Open Data Tampere Region et al. As a teacher, we had Miska Knapek. A nice and useful day at Itsenäisyydenkatu 23, a mid-town social hub kindly maintained by the co-op Tilanne (in Finnish).
IATUL 2014 conference around the corner, I’m busy writing the paper and putting up the prez on visualizing altmetrics. To test my beginner’s legs in D3, I decided to modify a clever graph of Journals by Asif Rahman – one of the examples in the D3.js Gallery – with data from PLOS ALM API.
How many PLOS publications are there with at least one author from Aalto University, and which ones are they? Web of Science answered: 86. With DOI’s at hand, I turned to PLOS. Thanks to prompt and clear advice by Martin Fenner, I was led to the right path with the API call.
My version of Asif’s graph replaces the timeline axis with a selection of different metrics, and the size of the circles is now scaled by column, not by row. I also tweaked the colors to follow the PLOS style, where metrics are grouped in Views, Cited, Saved and Discussed.
To avoid delay in loading time, I am using here a local JSON file, returned by the API a couple of days ago.
