[SSR] Cannot read properties of undefined (reading 'Event')

[Jannchie]

During SSR rendering, an error occurs: Cannot read properties of undefined (reading 'Event'). The specific location of the error is in: plot.js:183:59. https://github.com/observablehq/plot/blame/90a56897cabda400e2b7537f8ecbbd2cebd18f7f/src/plot.js#L183

The reason might be that in the SSR environment, a virtual implementation of the Document element is needed. However, the example provided (which I referenced from this Observable example) is somewhat outdated.

I added the following line of code in the constructor of Document, to work around this issue:

class Document {
  constructor() {
    this.documentElement = new Element(this, 'html');
    this.defaultView = { Event }; // workaround
  }
  // other things
}

Perhaps the example file needs to be updated?

I just found the PlotRender in official vitepress doc is working fine and applied the above workaround..
