# Data Visualizations Created Using Vega Visualization Grammar

This repository contains source code and data for data visualizations created by Andrzej Leszkiewicz using Vega visualization grammar.

Each folder in this repository usually contains one visualization example: one Vega specification file (JSON) and at least one data file (CSV or JSON). Some examples may be presented in multiple variations and therefore have more than one Vega specification file per folder.

Live visualization, generated on the fly using the files from this repository:

The following images are just snapshots of the visualizations. They may be outdated and incomplete.

Vega visualizations can be embedded into reports/dashboards created using one of the following tools:
- Power BI ([Deneb, certified custom visual for Power BI](https://deneb-viz.github.io/)) - Microsoft
- Looker Studio - Google
- OpenSearch Dashboards - Amazon Web Services
  
As well as they can be embedded into any web page or app.
