cufflink connects plotly with pandas to create graphs and charts of dataframes directly. choropleth is used to describe geographical plotting of USA. choropleth is used in the plotting of world maps and many more.
Command to install plotly:
pip install plotly
Below is the implementation:
# 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) |
