DATAWRAPPER GRAPHICS

An (unofficial!) package for Datawrapper that allows you to interface between your pandas dataframes and Datawrapper locator maps, charts, and folders in Python.

INSTALLATION AND SETUP

Install using pip:

pip install datawrappergraphics

Datawrappergraphics uses Datawrapper's API to interface with Datawrapper. In order to use it, you need to generate an API token with the following permissions:

• Auth: read/write
• Chart: read/write
• Folder: read/write

This token can be generated in settings > API-Tokens. There are three ways to authenticate:

1. By default, Datawrappergraphics will look for an environment variable called DW_AUTH_TOKEN.
2. You can upload a auth.txt file in your project's root directory containing only your authentication key (don't forget to add this file to your .gitignore!).
3. You can pass your token on instantiation using the auth_token arg.

Once you've authenticated, you're good to go!

USAGE

There are currently two main classes that can be implemented using this module:

• Map - This is a datawrapper locator map.
• Chart - This is a datawrapper chart.

Each of these classes inherits from the DatawrapperGraphic class, which is not meant to be implemented directly.

Classes can be implemented by using:

import datawrappergraphics

chart_id = "AbBe1"

map = (Map(chart_id)
        .data(aPandasDataframe)
        .head("A cool headline for your chart")
        .deck("A great looking deck, or subheadline, for your chart".)
        .footer("This is a note")
)

GUIDE

Some simple usage patterns. Get started by importing the package:

import datawrappergraphics as dwg

Create a new chart.

dwg.Chart()

Copy an existing chart.

This will create a brand new chart by copying another chart. Useful if you've made a "template chart" and want to create a bunch of charts using different data based on that template.

dwg.Chart(copy_id="AbCd1")

Upload data to an existing chart. ==========================

Data is uploaded as a pandas dataframe. Charts do not require any special columns, so go wild with it.

dwg.Chart(chart_id="AbCd1").data(df)

Upload data to an existing locator map ==========================

The Map class is used to interact with locator map data. Your dataframe has to have a few required columns:

• Type: Either "point" or "area", depending on whether the row is a point marker or an area.
• latitude/longitude or geometry: Point markers use two columns to locate: latitude and longitude. Area markers need a geometry column with WKT in the rows.

When you're uploading your data, you can specify a number of optional columns to control how your marker points show:

• Point markers:

  • icon: Specify the id of any icon available in Datawrapper's locator maps. Default: circle.
  • markerColor: What color the marker shows up as. Default: #C42127.

• Area markers:

  • fill: A 6-digit hexcode or a boolean value that controls the fill color or visibility of the marker fill. Default: #C42127.
  • stroke: A 6-digit hexcode or a boolean value that controls the stroke color or visibility of the marker stroke. Default: #C42127.
  • fill-opacity: A float value that controls the opacity of the fill. Default: 0.5.
  • stroke-opacity: A float value that controls the opacity of the stroke. Default: 1.0.

The names of all columns are case sensitive!

dwg.Map(chart_id="AbCd1").data(df)

List charts in a folder

This is particularly useful if you're editing a large number of charts and want to iterate through charts in a folder.

dwg.Folder(folder_id="12345").chart_list
