I started bubblesjs to create fast lightweight charts that could be used in places where page load time is critical like journalistic sites, ex. New York Times. bubbkesjs is < 20KB gzipped and supports a varity of charts and widgets. Check out some of the examples or data stories to see it in action.
I think there is a space in the data visualzation market for light weight charts. There are a number of players or enterprise charting but those libraries are too heavy usually in MBs. Would like to know the communities thoughts on this. Thanks!
