TextHeatmaps.jl is a lightweight Julia package for visualization of numerical values associated with text.

## Installation

To install this package and its dependencies, open the Julia REPL and run

```julia-repl

]add TextHeatmaps

```

## Example

Assume you have the following values associated with words in a sentence:

```julia

text = "I loved the concert but not the opening act"

words = split(text)

val = [0.1, 2.5, 0.0, 0.3, -0.6, -1.4, 0.0, 0.1, -0.1]

```

These values could for example come from a sentiment analysis model.

Using the heatmap function, we can visualize the values:

![Heatmap in Julia-REPL][heatmap-repl]

This not only works in the REPL, but also as HTML output in notebooks and on websites:

![Heatmap in Pluto][heatmap-pluto]

The color scheme of the `heatmap` is customizable:

![Heatmap in Documenter][heatmap-settings]

For more information, refer to the [package documentation](https://Julia-XAI.github.io/TextHeatmaps.jl/stable/).
