The goal of plotly.py is to provide a pleasant Python interface for creating figure specifications for display in the Plotly.js JavaScript library. In Plotly.js, a figure is specified by a declarative JSON data structure, and so the ultimate responsibility of plotly.py is to produce Python dictionaries that can be serialized into a JSON data structure that represents a valid figure.

As a concrete example, here isthe Python dictionary that represents a figure containing a single bar trace and a title.

As a concrete example, here isa Python dictionary that represents a figure containing a single bar trace and a title.

import plotly.ioas pio

fig= {

"data": [{"type":"bar",

"x": [1,2,3],

"y": [1,3,2]}],

"layout": {"title": {"text":"A Bar Chart"}}

}

import plotly.ioas pio

pio.show(fig)
