The eco system of vis in JavaScript is prosperous, there are lots excellent libs such as vega, echarts. I got many ideas from them.
Flutter lacks such charting libs, so Graphic is a good alternative I think.
Animation is under construction, it will come soon.
The map is not supported yet, maybe added in the feature .
It is based on dart canvas graphical system, which makes it performs as good as native mobile (SVG is not natively supported in mobile or flutter). But the grammar of dart canvas is very like SVG.
I am upgrade the graphical engine for animation. I believe any one who knows about SVG will find it very easy and familiar to use.
The idea of import SVG strings/files is a good idea, I shall consider it.
I am glad you'v paid attention to it. Graphic did evolve a lot in the past years and is still evolving. Hope you could keep an eye on it, maybe one day it could meet your needs.
