Plotters 0.3 is now released

Hi everyone, after a long time working, I am very happy to announce the new major update of Plotters, the plotting library in pure Rust.

Here's some details about this major release.

Since this version, some major features are added, including 3D plotting, some other improvements were made.

More importantly, since Plotters 0.3, we are able to support third-party crate used as drawing backend which allows anybody targeting Plotters to anything they want very easily.

Check the change log and release notes for more details.

Hope you enjoy this new release, and all feedback are warmly welcomed!
