Hexbins also mean fewer DOM elements on the page.
Just how many DOM Elements do we create to visualize the 2000 records in our diamonds.json dataset?
Pasting document.getElementsByTagName('*').length into the JavaScript console in Chrome’s DevTools tells us that there are 2279 elements on the page for this hexbins-only example.
In contrast, our one-circle-for-every-datapoint encoding method in Correlation Matrix IV creates 84072 DOM elements.
