Plotly: histogram with no fill color

I'm using Plotly's graphic_objects.Histogram. I am trying to draw several histograms on the same plot. I'm not satisfied with the results of the 'overlay' option. I would like to draw histograms with no fill colour like in this example, with only the borders of the boxes drawn.

I was trying to fiddle with marker.pattern options but this doesn't seem to work. What would be the way to accomplish this, if this is possible?

Expanding on @Oxbowerce's suggestion, this gives an OK look (however, ideally I'd like to only use the 'roof' of each bin and not the vertical lines, I suspect that's not possible though)

fig = px.histogram(...)
for i in range(len(fig.data)):
    fig.data[i].marker.line.width = 3
    fig.data[i].marker.line.color = fig.data[i].marker.color
    fig.data[i].marker.color = "rgba(255, 255, 255, 0)"
