Introductory mapping exercise

Context

Related to https://github.com/Police-Data-Accessibility-Project/data-projects/issues/17

We have prior analysis done in this repository: mj-decriminalization/analysis/grief to action/Final_Marijuana_Visualization.ipynb

This issue is about doing some basic mapping and getting familiar with the tools in the process. We will mostly be stealing and modifying code from similar projects / chatgpt, so python knowledge is not critical.

Tasks

Research

• [x] check out the source data for arrests and citations
• [x] read about Bokeh and Python or mapping using python notebooks in general

Getting started / environment setup

• [x] download pycharm, an "IDE" / code editor geared toward python projects
• [x] install github desktop and clone this repository
• [x] open the above file in pycharm, and "run" it to verify that the analysis is generated as it looks in the web version linked above. note that it references a file in github with merged arrests and citations.
• [x] make a new branch in github called mj-mapping, so that your changes are contained to that branch
• [x] check off these tasks and leave a comment checking in when this is complete, or comment if you have issues along the way!

Mapping data

• [ ] grab the new fall 2024 template file once https://github.com/Police-Data-Accessibility-Project/caasi-help-desk/pull/29 is merged
• [x] in your copy of the file, delete everything after the line containing mj_data_df = pd.read_csv(url, low_memory = False)
• [ ] see if you can modify the file using research about bokeh and these chat gpt suggestions to make literally any kind of map appear with data from the spreadsheet
  • I'm anticipating you will get stuck here, and we can figure out what's next.
  • use X and Y columns for location, and record_type for arrests vs citations
• next steps TBD; likely will involve comparing police zones, or overlaying arrests and citations in a heatmap across pittsburgh with zone or neighborhood overlays

The file is giving me error messages in PyCharm, but the visualizations are showing.
