I've added a fun little slider to https://www.mindat.org/elements.php

Jolyon,
Showing Mendeleev's collection is just fantastic! It is wonderful to know that such a scientist was also a collector. Thank you.

That's awesome! Been wanting to see a feature like that somewhere.

Cool!  Maybe make the height of the slider bar vary to indicate the number of elements discovered that year or decade to show trends.
