Graphvizer Viewer

An image viewer for Graphvizer

Introduction

Graphvizer is a plugin for Sublime Text 3 to render image in real-time while you are writing. If you have tried it, you may find that its convenience is limited because Sublime Text is not a suitable image viewer as mentioned in issue #14.

Sublime Text can view image but it doesn't support zoom or pan the image. If the image is large, it will be very difficult to navigate it. That's why I write this viewer. GraphvizerViewer is an awesome supplement of Graphvizer. I bet you will like it.
