EOSC: the European federated infrastructure that accelerates open science
In recent years, the need for the international scientific community to have agile mechanisms to share research results in order to respond to challenges such as pandemics, the climate crisis, biodiversity loss or the energy transition has become clear. In this sense, R+D tasks have become…
Observable + D3.js: the ideal open-source combination for your data visualizations
Data visualizations act as bridges between complex information and human understanding. A well-designed graph can communicate in seconds data that would take minutes or even hours to decipher in tabular format. What's more, interactive visualizations allow each user to explore data from their o…
