longterm google charts user. This has attraction. Good eye candy feel, responsive.

There are some specific things google charts do, like mark out kashmir and other disputed territories differently depending on your origin IP/AS so you don't fall foul of Indian law.

There are some things google charts don't do, like re-center maps off the meridien they think is best. Scaling geo charts for the pacrim island nations is also very hard. No good choices there perhaps.

Is there a migration guide?
