Learn to visualize Article Level Metrics data using Google Fusion Tables and Google Charts

All articles published by the Public Library of Science have Article Level Metrics collected. These metrics include citation counts, web views, online bookmarks, and more. The metrics are available through the PLoS ALM API and in a bulk CSV file.

The CSV data can be uploaded to Google Fusion Tables, a free data hosting service that allows web-based browsing, filtering, and aggregation. The Fusion Tables API supports SQL-like queries and integrates tightly with the Javascript Google Charts library allowing visualization of query results in a web browser.

The advantage of JS is that it is crossplatform and works in any web browser, and allows interaction with the data.

Google Charts can visualize data from Fusion Tables with Javascript.

A complete copy of the PLoS Article Level Metrics data is published in a Summary Excel File. While the API is updated more frequently, the .xls file provides all the data in one download.

The updated .xls file is plos-alm-v5-09182011.xls dated September 18, 2011. The previous version V4 was plos-alm-v4-11302010.xls from November 30, 2010.

This new version of the summary PLoS Article Level Metrics file has also been uploaded to Google Fusion Tables.
