Bubbles not showing up

I read data from a google spreadsheet and render it using Plotly.newPlot() on this page here -

However, the bubbles that I expect to see are not appearing. I expect the bubbles to be as rendered here -

Can someone please give me a clue as to what could be the reason that it is not rendering the bubbles?
