Visualizing using markup

The item.markup() method combined with collection.out(its.markedUpText) provides a mechanism to annotate text for visualization. This is completely medium agnostic, which means you can either visualize using HTML, SVG or even the classic unix terminal. Consider the following text:

const text = `Its quarterly profits jumped 76% to $1.13 billion for the three months to December, from $639million of previous year.`;
const doc = nlp.readDoc( text );

Highlight the entities in the above text and then see the marked-up text:

doc.entities().each((e) => e.markup());
doc.out(its.markedUpText);
// -> Its quarterly profits jumped <mark>76%</mark> to
//    <mark>$1.13 billion</mark> for the <mark>three months</mark> to
//    <mark>December</mark>, from <mark>$639million</mark> of <mark>previous year</mark>.

This returned the original text with every entity annotated with the HTML <mark> tag. This text, when viewed as HTML appears as:

Its quarterly profits jumped 76% to $1.13 billion for the three months to December, from $639million of previous year.

The item.markup() accepts two parameters — beginTag and endTag. Their default values are <mark> and </mark> respectively.

Similarly it is also possible to highlight items on the console by using color codes to set the values of begin and end tags in the item.markup() method.
