Graph showing on IPad and Phone, not showing on desktop Chrome and Firefox

The link is https://dfwcityhomes.com/full-and-flat-fee-mls-listing-service/best-time-buy-sell-home/

I have been able to display a chart. I copied and enlarged the chart and this started happening. I have cleared browser cache and that did not resolve the problem.

I have searched the forum and updated all themes, plugins, browser, wordpress to latest releases.

If you inspect the page, <div id=”visualizer-20565-1515573485″ class=”visualizer-front visualizer-front-20565″></div> is not displaying.

Let me know if I can provide additional info. Please advise.
