Adjusting Layout Properties

You can create beautiful, interactive, and engaging visualisations like this one with Plotapi in any programming language.

Preamble

In [1]:
from plotapi import Terminus

Terminus.set_license("your username", "your license key")

Introduction

Let's take a look at some parameters that control the layout of our diagram.

As we can see, we have set our license details in the preamble with Terminus.set_license().

Dataset

Terminus expects a list of dictionary items, these will define the flow of pixels between a source and a target.

In [2]:
links = [
    {"source":"England", "target":"Germany", "value": 1000},
    {"source":"England", "target":"France", "value": 3000},
    {"source":"England", "target":"Spain", "value": 5000},
    {"source":"England", "target":"Italy", "value": 4000},
    {"source":"England", "target":"Japan", "value": 800},

    
    {"source":"Ireland", "target":"Germany", "value": 3500},
    {"source":"Ireland", "target":"France", "value": 3750},
    {"source":"Ireland", "target":"Spain", "value": 1750},
    {"source":"Ireland", "target":"Italy", "value": 5000},
    {"source":"Ireland", "target":"Japan", "value": 400},
]

We can add many source's and target's! As they increase, we may need to adjust Terminus layout properties to accomodate the diagram's size and throughput.

Visualisation

We can modify the width, height, and margin of our diagram.

The margin parameter can be a dictionary that defines the size of the top, _right, bottom, and left margins - or - it can also be a single float to imply an equal margin of that size.

By default a Terminus diagram is centered, but this can be disabled with center=False.

Here we're using .show() which outputs to a Jupyter Notebook cell, however, we may want to output to an HTML file with .to_html() instead. More on the different output methods later!

In [3]:
Terminus(links, width=800, height=500, margin=100).show()
