Hi Daniel, Tim's colleague is here. What we're ultimately looking for is a way to have a nice start-up animation, like in Chart.js (http://www.chartjs.org/). Google Visualization API does have transition animations but they haven't been working that well for us for a couple of reasons:
- It looks like you have to take a two-phase approach if you want to have some sort of start-up animation: you first need to set everything to zero and then (after a short delay), update the chart with the actual values. I think this is a bit hacky and it's accompanied by not very nice user experience (you can see the chart area/bars/lines flickering sometimes). - Transition animations are quite slow (low FPS) if you have three or four charts on the same screen and they're animating at the same time. We're targeting variety of user agents (both desktop and mobile) although we officially support only relatively modern ones (for example, we don't officially support Internet Explorer 9). I was initially thinking about decorating the Google Visualization API a little bit to allow us to apply SVG animations (via a third-party library) when the chart gets rendered. Looking forward to your thoughts. Best regards, Pavel.
