Plotapi, beautiful by default.

Let plotapi do the heavy lifting – enabling beautiful interactive visualisations with a single line of code (instead of hundreds).

Different Pipe Alignment

Preamble

In [1]:
from plotapi import Terminus

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

Introduction

Pipes are aligned to the top-left by default, however, changing their alignment with pipe_alignment can often significantly improve the presentation of a Terminus diagram. The pipe_alignment works regardless of the vertical or bundled settings.

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

The options available for pipe_alignment are: top, bottom, justify, and camel.

Let's demonstrate pipe_alignment=camel on a vertical Terminus diagram first, and then illustrate a few different configurations as PNGs.

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, vertical=True, width=500, height=600, pipe_alignment="camel").show()

You can do so much more than what's presented in this example, and this is covered in other sections. If you want to see the full list of growing features, check out the Plotapi API Documentation.
