data and information visualization

What can you find on this website?

This page presents a range of infographics and other information and educational material, particularly focused on the topic of the environment. These materials can be downloaded in high resolution for further use. There is also the option of direct sharing to social media, sorting, filtering and searching for materials, a transcript is available for each and the materials are categorized by their topic and keywords.

The materials are intended for various target groups from general public, media, schools etc. They are licensed as Creative Commons (CC BY 4.0), meaning they can be freely redistributed provided that the source is cited.

The project is a fully non-commercial and the materials provided are the result of the effort to spread knowledge about these topics.

Knowing and understanding = possibility and effort to search for solutions.



Weather and Climate

Air Quality









Update: Why is Air Quality Important?
Maximum air temperature
Inhaled and exhaled air
Chemistry of fireworks – colors

Data is like a fuel of the 21st century. Data analysis is then like a combustion engine. Placing data analysis in context and its explanation is like a map that tells one where to go and makes the data viz useful.

  • What is infoviz?

    Infoviz is an abbreviation for "information visualization". Infoviz is the process of displaying data and information in an easy-to-understand form. It is a more complex process than simple data analysis or visualization, and recently it has become very popular to present data in this form.

    The process of information display is often preceded by a process of data collection or research, data analysis and data visualization. Data analysis involves processing the data (using statistical methods) so that various questions can be answered from the data. Data analysis is often followed by the process of data visualisation - creating different types of graphs or data visualisations. The information visualization process goes one step further - it adds labels, text, and other elements to the data visualizations to explain the issue or answer the original question in an understandable way. For information visualization it is not enough to have just a knowledge of the statistics and the data set, for example, knowledge of the target group is also needed to create an output that is understandable to that group. Often different data visualizations, text, maps or other elements such as images or icons are combined. The output is also adapted to the target medium in which the visualisation is presented. For example, if it is a web page, various interactive elements can be used (zooming in on graphs and maps, selecting the information to be displayed, etc.). If, on the other hand, the output is intended for printing, the output needs to be adapted for this purpose.

    The output of an information visualization can be, for example, an infographic, a poster, a web page, a report etc.
