Tailing dams
After a Brazilian dam storing mine waste, or tailings, collapsed and killed over 240 people, the Church of England, an investor in mining companies through its pension funds, requested data on these dams. Reuters compiled the data from publicly posted responses on corporate websites and looked at where high-risk dams are located, the factors that determine risk, which mining companies own these dams and more. Tools used: JavaScript, CSS, HTML, Illustrator, Photoshop, QGIS, jQuery, d3.js, Python (pandas).
