## Description

Hellocharts-android is a data visualization library and charting framework for Android applications. It provides a collection of custom view components used to render datasets as visual elements, such as line, column, and pie charts.

The library supports interactive visualizations that allow users to navigate data through touch gestures, including pinching, scrolling, and panning. It also includes built-in capabilities for animating data points and chart elements to create smooth visual transitions during dataset updates.

The framework covers a broad range of visualization needs, including chart generation, axis configuration for scales and labels, and the rendering of graphical plots for application analytics and reporting.
