    <p>I am an iFrame of the page located at <a href="https://neodash.graphapp.io/embed-test.html" target="_blank">https://neodash.graphapp.io/embed-test.html</a></p> 
    <p>I'm embedded directly into a dashboard, and dynamically passed the user-made parameter selections.</p>
    <p>I will not refresh when selections are updated, but, I can see variables change.</p>
    <p>You can use me to embed external visualizations that are updated together with other charts.</p>
    <b>Your dashboard variables:</b>
    <pre></pre>

    var pre = document.querySelector('pre');
    
    var applyHash = function() {
        const hashValue = window.location.hash.substr(1);
        var output = "";

        searchParams = new URLSearchParams(hashValue);
        searchParams.forEach(function(value, key) {
            output += key + ": " + value + "\n"
        });
        pre.textContent = output;
    }
