This is a simple web application that allows the generation of map visualizations. All the processing happens on the client and the server can simply be a static web server.
This is only a small project I started, to learn lit-html/LitElement, WebGl and try out the Rust programming language a bit more.
A example of what is possible can be found here:

If you run the application yourself you will have to clone the repository, download
and extract geojson data and then bundle using yarn. After bundeling you simply have
to serve the contents of the dist/ directory.
$ git clone https://github.com/rolandbernard/geo-draw
$ cd geo-draw
You can download the required data from eighter https://osm-boundaries.com/ or
https://www.geoboundaries.org/. You can also use other soures of geojson, as long as
they use the same properties for the name and id as eighter of the other two sources.
You should put your data into the data/ directory.
$ mkdir data
$ cp <your data> data/
Setting up this web application requires extracting geojson data into a usable and more
importantly compact format. This can be done using the Rust program in data-extarct/.
The data should be in data/ and will be extracted to static/data/. To run the extraction
program simply go into data-extract/ (using: cd data-extract/) and then run the program
using cargo (cargo run --release).
To bundle the project simply use yarn:
$ yarn dist
