Make graphs updateable

[borissmidt]

I've used the ammonite plotly implementation and for each plot it creates a new browser screen so it isn't possible to show the progress of something or visualize a stream.

It would be nice if you had a plot output which you could update with a new plot.

so

val scatter = Scatter(Seq[Double](1, 2, 3), Seq[Double](2, 3, 4))
scatter.plot("hello", addSuffixIfExists= false)

this could become:

val plotWindow = PlotWindow()
val scatter = Scatter(Seq[Double](1, 2, 3, 4), Seq[Double](2, 3, 4, 5))
plotWindow.update("plot", scatter)
val scatter2 = Scatter(Seq[Double](1, 2, 3), Seq[Double](2, 3, 4))
plotWindow.update("plot", scatter2)

I'm not sure how it could be implemented and i agree that it goes against the immutability idea. But it would make it better to have some interactive visualization of the data.

    Plotly.plot(
      out.toString(),
      plot.toSeq,
      lay,
      openInBrowser = false,
      addSuffixIfExists = false
    )

you can add openInBrowser = false, that will update the file without open a new browser.
Then you manually open the file with a browser, and install pluging in browser to auto update the page.

However, I don't really like this solution.
For instance I have a output file with many data, and each second I rewrite the entire file for just update one data to my disk. I have a SSD disk, it isn't good for its lifetime
I prefer a solution like append the new data to file, or I update the html file in the RAM, the browser directly read the html file in the RAM. But I don't know how do it.
