d3 Map Renderer [![license](http://img.shields.io/badge/license-MIT-brightgreen.svg?style=flat)](https://github.com/sbenten/d3MapRenderer/tree/master/LICENSE)
==

A python **QGIS** plugin to export of polygons, polylines and point vector layers from shapefiles to topojson for display within a web page using the [d3.js](http://d3js.org/) JavaScript library, with additional options of popup information, charts from [c3.js](http://c3js.org/) and a map legend.

Pre-requisites of [QGIS](http://www.qgis.org/en/site/) and the [Node.js](https://nodejs.org/) topojson package.

## Pre-requisites

Download and install [QGIS](https://www.qgis.org/en/site/forusers/download.html).

Download and install [Node.js](https://nodejs.org/download/).

Once Node.js is installed, you will need to install the topojson package which converts Geographic Information System shapefiles to d3's topojson format.  This can be done by opening a command prompt or terminal (depending on your operating system), and typing:

```
npm install -g topojson
```
This command downloads the topojson package and registers it for use on the command line.

d3 relies heavily on [JSON](https://en.wikipedia.org/wiki/JSON) files for loading data, and topojson is no different. To see the results of an export via this plugin you will also need a web server, as restrictions in modern web browsers prevent json files being loaded from the local file system. So if you want to view the results of the export before uploading to a website in the cloud (recomended), you will need a web server.

If you haven’t already got a web server already installed use [http-server] (https://www.npmjs.com/package/http-server) for Node.js. Install it by returning to that command line and typing:
```
npm install -g http-server
```
http-server is started and stopped via the command line, and it is as simple as changing to the directory where you are going to output your d3 maps (this will be the root of the local web site), and starting the server. For example, on Windows this would be the following two commands (obviously using your own directory path):
```
cd c:\Users\Simon\Documents
http-server
```
That wasn’t so bad was it?

## Installation

Download from the QGIS plugin repository. Currently flagged as an experimental plugin.

If you want to try the bleeding edge version, [download the zip](https://github.com/sbenten/d3MapRenderer/archive/master.zip) direct from GitHub, and extract the contents into your QGIS python plugins directory (which on Windows is something along the lines of C:\Users\Simon\\.qgis2\python\plugins\). Rename the folder from d3MapRenderer-master to just d3MapRenderer and you will find the plugin listed along side the others in the QGIS plugin repository.

## Logging issues and feature requests

The [issue](https://github.com/sbenten/d3MapRenderer/issues) log is to be used for reporting problems with the plugin and for feature requests and ideas. It is **not** a support forum. Nor is it the place to log problems with topojson, d3 or c3.

Before reporting an issue, please do the following:

1. Search for existing [issues](https://github.com/sbenten/d3MapRenderer/issues) to ensure you're not creating a duplicate.

1. When posting the issue, please use a descriptive title, include the plugin version and relevant details about what was trying to be achieved with the plugin.

1. Also, please post the details from the Log Messages Panel within QGIS, and if possible a link to download the pertinent shapefiles. A sample of the log messages for the plugin:
