data="" attribute

When the data to be handled is basic, the data attribute can be used directly to indicate keys and values separated by comma (,) or semicolon (;). It is useful with basic visualizations, like some of the examples we use in this guide, but is not sufficient when you want to make more complex situations.

WARNING

The .data property has the key and values defined in the attribute, but if this property is updated, the attribute is not updated. It is a unidirectional reflection, from attribute to property, but not in the opposite direction.
