I used page.waitForSelector(). With the waitForSelector method you may tell the page object to suspend execution until an element is visible. So basically if you render an SVG with an id “result”, you could just say await page.waitForSelector('#result') and after it resumes, the rendered result may be caught via screenshot or whatever.

You may find more about the waitForSelector API here: https://github.com/GoogleChrome/puppeteer/blob/master/docs/api.md#pagewaitforselectorselector-options
