All CSS for the visualisation class can be found here: https://waci.surge.sh/assets/css/waci.css. This is likely to change during the project so it might be best to hotlin to this URL initially and then incorporate the finalised code later on.
Code sample:
<section id="visualisation" class="visualisation"> <div class="visualisation__wrapper"> <iframe title="Title of visualilisation" src="https://app.powerbi.com/view?r=eyJrIjoiNjQxZGVmYTgtNTc2OS00ODdlLTg1N2EtMzc4ODExYjljNWFlIiwidCI6IjY5ZjdkZTk4LWI0ODctNDcxMS1hN2YzLTgyZjM4MjU0YmFkZCIsImMiOjh9&pageName=ReportSectionc2e153efe766f264fe32" frameborder="0" allowFullScreen="true"></iframe> </div> </section>
