Handle empty data in heatmaps

[Sanjay-Sahu-Bandla]

Is there any way to handle the empty data like showing "No data is available" when there's no data given for the heatmap

Example:

var data = [
  {
    z: [],
    type: 'heatmap'
  }
];

Plotly.newPlot('myDiv', data);

Instead of showing an empty heatmap with x-axis, y-axis lines, it should show a label text like "No data is available"

If this feature is not available, it would be great to add such feature.
