# ConstituencyMap

A map of UK parliamentary constituencies created in D3

![UK parliamentary constituencies, coloured by elected party](./assets/map.png)

## How to run

1. Clone this repository

2. Navigate to the [`map`](./map) directory in the repository and run a server. This can be done by:

    - Using a plugin on a JavaScript IDE

    - Run `python -m http.server` in the terminal

3. Navigate in a browser to the localhost which contains the application

## TODO

- [x] Offset constituency circles on alternate rows

- [x] Fit map to SVG size

    - [ ] Do this dynamically (without hard-coded numbers)

- [x] Combine map data with 2019 parliamentary results (pre-JS/d3)

    - [ ] Do this step in D3

- [ ] Fill in missing constituencies in hexmap

- [x] Colour circles by party

- [ ] Add legend

- [ ] Use hexagons instead of circles

- [ ] Make constituencies interactive

## Data

- `uk_hex.csv`

    - Coordinates of UK parliamentary constituencies (2017 boundaries) in hexmap format

    - Created by [ODILeeds](https://odileeds.org/projects/hexmaps/constituencies/),

    released under MIT license

- `HoC-ge2019.csv`

    - Results of the 2019 UK General Election

    - Provided by [HoC library](https://commonslibrary.parliament.uk/research-briefings/cbp-8749/)

- `combined_ge2019.csv`

    - Merged `uk_hex.csv` and `HoC-ge2019.csv`

    - Removed some unused fields, such as individual part votes, from combined dataset

    - **Note**: Not all constituencies are present in both files.

    I believe this is because the ODI map uses the old (2017) boundaries.

    The hexmap will need to be updated.
