I am developing a basic chart library and I would like to know some of your most desired features within such library.
The main reason for me was the need for a lightweight chart and the ability to easily change the chart's look and feel.
That's why I wanted to create a HTML based chart, which can be customised using CSS. Here's a sneak peek:

Responsive is very important and flexibility. Also different kind of charts, but mainly stacks and lines.
Is it possible to create it with just HTML, CSS and JavaScript without SVG and still get all the features? Sounds like it could boost performance.
I'm currently using ChartJS.
