alt Hacker NewsIt's not just 2 MB of JS. I'm describing ALL traffic, also the JSONs received, CSS, images, everything.
Besides, we show many charts, and believe me when I say: financial people are PICKY when it comes to chart functionality. It needs to have EVERYTHING or you're not considered serious.
It sounds like you're developing a turn-key highly interactive application for a very particular niche of users. It makes sense that for them the tradeoff of downloading 2MB of Javascript makes sense versus enjoying their bells and whistles.
But for the rest of the internet, where users sometimes view your page with decrepit browsers riding on hobbled connections, 2MB is too much. Worrying about these people is not blowing it out of proportion. It's basic human decency.
