A Periodic Table Visualizing the Year & Country in Which Each Element Was Discovered

On the “Data is Beau­ti­ful” sub­red­dit, a user named Udzu post­ed a visu­al­i­sa­tion of the Peri­od­ic Table of Ele­ments that high­lights the year and coun­try in which each ele­ment was dis­cov­ered. You can view it in a larg­er for­mat here. Elab­o­rat­ing on how the graph­ic was made, he adds (his words, not mine, fol­low):

• The year and coun­try of dis­cov­ery are tak­en from Wikipedia and are based on when the ele­ment was first observed or pre­dict­ed rather than when it was first iso­lat­ed.
• The pri­or­i­ty for the dis­cov­er­ies is often con­tentious. The visu­al­i­sa­tion uses the list­ings cur­rent­ly in the Wikipedia arti­cle, with no claim as to their accu­ra­cy.
• The coun­try is typ­i­cal­ly both the cit­i­zen­ship of the dis­cov­er­er and the loca­tion of dis­cov­ery. Excep­tions include Hafni­um (dis­cov­ered by a Dutch and Hun­gar­i­an duo in Copen­hagen) and Radon (dis­cov­ered by a British and Amer­i­can duo in Mon­tre­al); these are list­ed under loca­tion.
• Coun­tries and flags are of the mod­ern equiv­a­lents when appro­pri­ate: e.g. Rus­sia rather than the USSR, UK rather than England/Scotland, and Mex­i­co rather than New Spain.
• The ety­molo­gies are also tak­en from Wikipedia.
• The leg­ends con­tain sum­ma­ry counts of the data. Good work, Swe­den.

Ranked in order, the UK could lay claim to 19 ele­ments, Swe­den and Ger­many to 18 each, France to 16, and Rus­sia and the Unit­ed States to 11 each.
