We’re all about beautiful vector stuff here at amCharts. That’s why we created our own, home-grown icons for our weather demos and especially our Weather Map tool.
You’re welcome to use them in your projects too, including commercial ones: they’re free under a Creative Commons license that only asks you to credit amCharts (see License below).
All icons are fully scalable, based on standard SVG and animated using CSS, with no JavaScript needed.
