## Introduction

To enable rapid transportation modeling and optimization, as traffic management researchers, we provide this free open-source tool for visualizing multimodal networks. Based on GMNS data format by [Zepha foundation](https://zephyrtransport.org/), plot4gmns is designed for reading and plotting multimodal data sets including transportation network files, demand and agent trace files.

## Requirements

- pandas
- shapely
- matplotlib
- numpy
- seaborn
- scipy
- chardet
- keplergl==0.3.2

## Install

```python
pip install plot4gmns
```

> Note
>
> - For Windows users, the _pip_ method might fail to install some dependencies. If errors occur when you try to install any of those dependencies, try instead to pip install their .whl files, which can be downloaded from the Unoffical Windows Binaries for [Python Extension Packages](https://www.lfd.uci.edu/~gohlke/pythonlibs/).

## Usage

Before starting, you must have prepared network files, including node.csv, link.csv, poi.csv, demand.csv, and zone.csv. The [osm2gmns](https://github.com/asu-trans-ai-lab/OSM2GMNS) package will help you quickly obtain node, link, and poi data, and the[ grid2demand](https://github.com/asu-trans-ai-lab/grid2demand) package will help you obtain network demand and zone information.

### Quickstart

**Step 1: generate multimodal network**

```python
import plot4gmns as p4g
mnet=p4g.generate_multi_network_from_csv(r'./datasets')
```

> After executing the above command, you will get an Html file, as shown below. More visual operations are supported on the web site..

**Step 2: show networks in different modes**

```python
# draw 'all' modes network and save to png file
cf = p4g.show_network_by_modes(mnet=mnet)
# show the figure on the current window
cf.show()

### Advance Usage

**Step 1: Show only network elements of interest**

The tool displays all elements by default, such as nodes, links, and POIs. If you want to display only the elements of interest, you can refer to the following example to modify the state of other elements before invoking the drawing command.

```python
# not show nodes
mnet.node_loaded = False
cf = p4g.show_network_by_link_lane_distribution(mnet=mnet)
cf.show()
```

<img src="https://github.com/PariseC/plot4gmns/blob/main/docs/media/network_by_link_lane_distribution2.png?raw=true" width="800" height="600" alt=" "/><br/>

**Step 2: Show different networks on one diagram**

By default, this tool will clear the original contents before drawing. If you want to draw different content on a graph, you can refer to the following example

```python
mnet.node_loaded = False
mnet.POI_loaded = False
cf = p4g.show_network_by_link_lane_distribution(mnet=mnet)
mnet.link_loaded = False
mnet.POI_loaded = True
cf = p4g.show_network_by_poi_attraction_distribution(mnet,fig_obj=cf)
cf.show()
```

**Step 3: Set the drawing style**

Users can refer to the following examples to adjust the color, size and other attributes of the image before drawing.

| mnet.style.zone_style.fontcolor       | str                     | zone label font color            |

```python
mnet.style.node_style.size = 3
mnet.style.link_style.linecolor = 'green'
mnet.style.poi_style.facecolor = 'gray'
cf = p4g.show_network_by_modes(mnet=mnet)
cf.show()
```
