This page shows an Interactive Dashboard that We've created while learning how to use the Vega-Lite programming language for interactive visualizations.
The Dashboard represents real data about the monthly number of registered cars per Brand in Portugal and the Registrations for Toyota in 2019 and 2020 are highlighted, which was provided by ACAP. (brief instructions on how to use the plot are provided at the bottom).

We will keep the data updated.
