Need a little help with embedding/static page

Thanks! But how can I get just the chart, not the code?

I just amended my question a good bit. There is an error in the console when I add this:

Runtime.load(notebook, (cell) => {
          if (cell.name === "chart") {
            return {
              fulfilled: (value) => {
                document.getElementById("chart").appendChild(value);
              }
            };
          }
        });
