 I needed an easy way to download SVG images created in [D3](https://d3js.org/) as PNG. I found that Mike Bostock made an [Observable Notebook](https://beta.observablehq.com/@mbostock/saving-svg) which solved the exact problem. the only issue was that some of the ways Observable handles DOM manipulation is not directly compatible with the browser. I modified the original code to be browser compatible.
 
-**Currently it requires that d3 is declared globally, but that may change in future updates.**
 **Below example also uses [FileSaver.js](https://github.com/eligrey/FileSaver.js) to save the blob, but it should be compatible with any blob saving library or implementation**
