Interactive

Vega 2.0 visualizations are interactive, allowing users to pan, zoom, and filter the data. This makes it possible to explore data in a more engaging and intuitive way. For example, a user could pan across a scatterplot to see how the data is distributed, or zoom in on a particular area to see more detail. A user could also filter the data to only show certain values, such as all the data points that are above a certain threshold.

  • Panning

    Panning allows users to move the visualization around by clicking and dragging. This is useful for exploring large datasets or for getting a closer look at a particular area of the visualization.

  • Zooming

    Zooming allows users to zoom in or out of the visualization by using the mouse wheel or by pinching and spreading on a touchscreen. This is useful for getting a closer look at a particular area of the visualization or for seeing the overall trend of the data.

  • Filtering

    Filtering allows users to filter the data by selecting certain values. This is useful for focusing on a particular subset of the data or for removing outliers.

The interactivity of Vega 2.0 visualizations makes it a powerful tool for data exploration and analysis. Users can easily explore the data, identify trends, and make informed decisions.

Scalable

Vega 2.0 is a scalable visualization library that can handle large datasets. This is important because it allows users to create visualizations of complex datasets without having to worry about performance issues. Vega 2.0 achieves scalability through a number of techniques, including:

  • Efficient data encoding

    Vega 2.0 uses efficient data encoding techniques to reduce the size of the data that is transmitted to the client. This can significantly improve performance, especially for large datasets.

  • Lazy loading

    Vega 2.0 uses lazy loading to only load the data that is currently needed. This can further improve performance, especially for large datasets that are not fully visible on the screen.

  • WebGL support
