下面是实现:
# Python program to plot
# geographical data using plotly
# importing all necessary libraries
import plotly.plotly as py
import plotly.graph_objs as go
import pandas as pd
# some more libraries to plot graph
from plotly.offline import download_plotlyjs, init_notebook_mode, iplot, plot
# To establish connection
init_notebook_mode(connected = True)
# type defined is choropleth to
# plot geographical plots
data = dict(type = 'choropleth',
# location: Arizoana, California, Newyork
locations = ['AZ', 'CA', 'NY'],
# States of USA
locationmode = 'USA-states',
# colorscale can be added as per requirement
colorscale = 'Portland',
# text can be given anything you like
text = ['text 1', 'text 2', 'text 3'],
z = [1.0, 2.0, 3.0],
colorbar = {'title': 'Colorbar Title Goes Here'})
layout = dict(geo ={'scope': 'usa'})
# passing data dictionary as a list
choromap = go.Figure(data = [data], layout = layout)
# plotting graph
iplot(choromap)
