Is there a tool to visualize the citation network which works with Google Scholar?
To my knowledge, at the time of writing, Google Scholar does not define an API to access data, so presumably no software exists. Beyond Google Scholar and the tools you've already mentioned, you could try  https://www.semanticscholar.org or https://aminer.org. (I'm a little unsure what you mean by citation network, so perhaps they don't satisfy your needs.)
