Use the Folium package and our Baltimore crime dataset to make an interactive data map of Baltimore Crime.
!pip install folium
import folium
import requests
import pandas
arrest_table = pandas.read_csv("http://www.hcbravo.org/IntroDataSci/misc/BPD_Arrests.csv")
arrest_table["race_new"] = arrest_table["sex"]
arrest_table["sex_new"] = arrest_table["race"]
arrest_table["race"] = arrest_table["race_new"]
arrest_table["sex"] = arrest_table["sex_new"]
arrest_table = arrest_table.drop('race_new', 1)
arrest_table = arrest_table.drop('sex_new', 1)
arrest_table = arrest_table[pandas.notnull(arrest_table["Location 1"])]
arrest_table["lat"], arrest_table["long"] = arrest_table["Location 1"].str.split(",").str
arrest_table["lat"] = arrest_table["lat"].str.replace("(", "").astype(float)
arrest_table["long"] = arrest_table["long"].str.replace(")", "").astype(float)
arrest_table.head()
folium package to create an interactive map of Baltimore
map_osm = folium.Map(location=[39.29, -76.61], zoom_start=11)
map_osm
You can find more information about folium here: https://github.com/python-visualization/folium/ and https://folium.readthedocs.org//
Add graphical elements to display the data. For instance, add circles, with colors indicating sex. Or circles with colors indicating race. Or anything else that strikes your fancy.
Embed your map in your iPynb notebook and submit to ELMS.
Prepare and an iPynb notebook that includes: (a) code to carry out each of the steps above, (b) output showing the result of your code (in this case the interactive map), and (c) a short prose description of your interactive map (i.e., what are you showing with this data and map). Remember, the writeup you are preparing is intended to communicate your data analysis effectively. Thoughtlessly showing large amounts of output in your writeup defeats that purpose. This will lead nicely into your final tutorial.
Working in groups in this project is encouraged but not required. If working on a group: (1) groups can be of 2 or 3 people, and (2) in all cases, names of peers who worked in the group should be included in the writeup.
As with all group work, and reflective of academic ethics code, there is an expectation that all group members will contribute equally in design, implementation and reporting of this work. If any student feels this expectation was not met when working on this project, they should contact the instructor team who will handle the situation as expediently and fairly as possible.
