Vega 2.0 is also well-suited for large datasets, and it can be used to create visualizations that are both visually appealing and data-driven.

Declarative API

Vega 2.0's declarative API is a powerful tool that makes it easy to create complex visualizations. With the declarative API, you can specify the visual appearance of your visualization using a JSON-based language. This makes it much easier to create visualizations that are both visually appealing and data-driven.

For example, the following code creates a simple bar chart using the declarative API:

{ "mark": "bar", "encoding": { "x": {"field": "category", "type": "nominal"}, "y": {"field": "value", "type": "quantitative"} } }

This code creates a bar chart with the x-axis showing the category and the y-axis showing the value. You can easily customize the appearance of the chart by changing the values in the "encoding" object. For example, you can change the color of the bars by adding the following code to the "encoding" object:

"color": {"field": "category", "type": "nominal"} }

The declarative API is a powerful tool that makes it easy to create complex visualizations. It is also very flexible, so you can use it to create a wide variety of visualizations, from simple charts and graphs to complex interactive dashboards.

Here are some of the benefits of using the declarative API:

• It makes it easier to create complex visualizations.
• It is very flexible, so you can use it to create a wide variety of visualizations.
• It is easy to learn, even for beginners.

Improved performance
