Nim Foreign Function Interface (FFI) bindings to [d3.js](https://d3js.org).
This is in development and there is still a lot to be written. There
is the ability to create a simple graph today. See
[examples/](examples/) for usage.
## Install
nim-d3 is available in [nimble](https://github.com/nim-lang/nimble).
`nimble install d3`
or if you have a `.nimble` file then add the following.
`requires "d3 >= 0.1.2"`
NOTE: Run `nimble search d3 --ver` to find out the most recent version
of the library.
## Documentation
Clone the repo and generate the docs
`nimble docs`

See the code for [example 5](src/pages/ex5.nim) for an example of
drawing a full chart.
## Building and Running
1. `nimble build` - build server
2. `nimble pages` - build js client pages
3. `./examples` - run server
4. Load [http://localhost:9000/](http://localhost:9000/) in browser.
