Vega和Vega-Lite是實現圖形語法的可視化工具, 類似於ggplot2。Vega和Vega-Lite通過添加一種用於探索複雜的數據集的新穎的交互語法，擴展了Leland Wilkinson（英語：Leland Wilkinson）的《Grammar of Graphics》。^[2]

Vega適合解釋性圖形的低級語言（與D3.js相同的用例），而Vega-Lite是適合快速探索數據的高級語言。 ^[3]Vega 用於多個數據可視化系統的後端，例如 Voyager。^[4]^[5]圖表規格（chart specification）寫成JSON形式，並在瀏覽器中呈現或導出為矢量圖或bitmap圖。多種編程語言已經支持使用Vega-Lite，例如Python包Altair^[6]以使其更易於使用。Vega和Vega-Lite語法和相關工具是由華盛頓大學交互式數據實驗室領導的開源項目，並以BSD-3許可證發布。^[7]
