(Data) Visualisation

Data storytelling through visualization is crucial because it transforms complex things which are inaccessible or hardly accessible into something we can more easily grasp - something we can see.

By combining data with visuals, such as graphs, charts, and maps, we can 1) either effectively explore or 2) effectively communicate patterns, trends, and outliers that might otherwise go unnoticed. This approach not only makes data more accessible and understandable to a wider audience but also enhances decision-making by providing a compelling narrative that connects the data to real-world implications.

Basic principles of data visualization in academic practice (Tomáš Marek, KISK), 2021, https://medial.phil.muni.cz/Play/12136

• Visual representations of data are powerful tools of scholarly communication. However, extensive research shows that they are not always used with sufficient functionality. This lecture and follow-up workshop will focus on the basic principles and rules of data visualization and its application. The lesson will focus on data visualization foundations and concepts, such as data-ink ratio, chartjunk or memorability. We will dive shortly into relevant cognitive science topics, such as pre-attentive processing or memory.

  • V současné době neuvěřitelného množství dat roste důležitost jejich správné interpretace a vizualizace. Právě proto je zde Information Designer neboli člověk, který data překládá do srozumitelného jazyka vizuálních sdělení. Jedním z nich je i Kristína Pšorn Zákopčanová, jež pracuje pro think tank Fakta o klimatu, Český rozhlas nebo PAQ Research.

  •  

    „Vzít data a dát je do grafu je snadné, ale často nás překvapí, že čtenáři nevidí to, co jsme zamýšleli,“ říká Kristína Pšorn Zákopčanová s tím, že vědět, co chceme říct, je klíčem ke srozumitelnosti. „I když to zní banálně, je to vlastně ta největší výzva. Například autoři často chtějí říct vše, což pak způsobí, že se sdělení ztrácí,“ dodává.
