    Here's a simple Plotly plot -

<!-- Plots go in blank <div> elements. 
    You can size them in the plot layout,
    or give the div a size as shown here.
<div id="testChart" style="width:100vw; height:calc(100vh - 100px);"></div>
-->
<div id="testChart" style="width:100%; height:100%;"></div>
<div id="testChart2" style="width:100%; height:100%;"></div>
<div id="testChart3" style="width:100%; height:100%;"></div>
