Descriptive name for your fiddle.
Edit to suit. (Only available to the logged in author.)

Author: mbourne

board ID: The ID for the JSXGraph DIV.

If you change this, make sure it's the same ID in this line in the script: ...JXG.JSXGraph.initBoard('my_new_id',...

You can only change this if you're the author. max-width: px A number only. aspect-ratio: e.g. 1.5 for wide, 0.7 for thin
A number only. max_height: e.g. 95vh; or 300px

Best for phone is:
calc(100vh - 1.5em)

(needs units)

You can only change this if you're the author.

<div id="jxgbox" class="jxgbox"></div>

#jxgbox {
  max-width: 600px;
  aspect-ratio: 0.4;
  
}

In the script, we have not set the pan: { needTwoFingers: true } option and so in this example, when viewing it on a phone, we can get "trapped" because the full screen can be taken up by the graph and swiping just moves the graph, not the page.

So it's best to set the max-height, like we've done in this fiddle (or not as good, set needTwoFingers).

This is the graph of y = 0.25x²sin(10x)
