Overlayed histograms with no fill color

Could you create a MRE for that?

I assume, the example from the bar-charts could be helpful:

Adapted:

import plotly.graph_objects as go

x = ['Product A', 'Product B', 'Product C']
y = [20, 14, 23]

# Use the hovertext kw argument for hover text
fig = go.Figure(data=[go.Bar(x=x, y=y,
            hovertext=['27% market share', '24% market share', '19% market share'])])
# Customize aspect
fig.update_traces(
    marker_color='rgba(158,202,225,0.0)', 
    # ^^ use a rgab string for the fillcolor and set the opacity to 0
    marker_line_color='rgb(8,48,107)',
    marker_line_width=3.0, 
)
fig.update_layout(title_text='January 2013 Sales Report')
fig.show()
