Visualising information

The guide to visualising information helps you to produce clear, concise visualisations that are consistent with the City of Helsinki’s communication guidelines. It will help you identify when visualisation is needed at all, or when text and photos alone will suffice.

The sections of the guide

Introduction to visualising information
Guidance for choosing a chart type for the most common use cases and basics about colours in visualisation.
Choosing a visualisation type
The visualisation method best suited to each purpose depends, among other things, on the nature of the data to be displayed, the number of series and data points to be compared, and the features of the data to be highlighted.
Common visualisation types
This section goes through the common types of charts and what kind of information they are used to represent.
Basic chart elements
General compositional principles for visualisations, mostly independent of the chosen chart type, are discussed in this section.
Colour use in charts
In visualisation, colours are not used for decoration, but to highlight meaningful differences. This section provides more detailed guidance on the use of colour.
