remove the weird whitespace around the plotly chart (Javascript)

I'm using the plotly library (Javascript) for plotting piechart, I'm using the flexbox for the layout. There's a huge whitespace on the right side of the chart as shown in image below: screenshot of issue

In the image above you could see whitespace on the right side of the pie chart. I've used the flexbox property : flex-grow to make use of all the space available. Why does flex-grow is not working here?

This happened because you set the width of the figure inside the first .r1 item. Flex box items are not meant to have a fixed width, even if it is computed from the flex box layout.

If you wait a little before calling make_pie() in the DOMContentLoaded handler, you can see the layout is as expected until you plot the figure.

To fix this you can add a relative width property to the flex items (especially those containing fixed-width elements), eg.

.r1 {
    border: 1px solid red;
    flex-grow: 1;
    width: 100%;
}
