According to [The International System of Units](https://en.wikipedia.org/wiki/International_System_of_Units):

> 
> The value of a quantity is written as a number followed by a space (representing a multiplication sign) and a unit symbol; e.g., 21 kg, 22 K.
> 
> 
> 

I am trying to create a plot honoring that space, but it seems I am unable to. Plotly will add no space between the quantity and the unit symbol (MN in this case, after adding the mega prefix):

```js
const data = [
  {
    x: ['A', 'B', 'C'],
    y: [20000000, 14000000, 23000000],
    type: 'bar',
  }
];

const layout = {
  yaxis: {
    title: 'Force',
    ticksuffix: 'N',
  }
}

Plotly.newPlot('plotDiv', data, layout);
```

```html
<head>
  <script src='https://cdn.plot.ly/plotly-2.6.3.min.js'></script>
</head>
<body>
  <div id='plotDiv'></div>
</body>
```

How can I add that space between the quantity and the unit symbol?

Ideally:

* It should work well with any prefix (including no prefix)
* The space should be represented both in the y-axis and in the hover label
