TTagCloud and TTagIndex components offer a 'tag cloud' navigation element for Embarcadero Delphi versions 7 to XE7. These visual components can be easily integrated into software.

The tag cloud (or tag index) can offer valuable data visualization for various kinds of information systems, ranging from simple databases to complex knowledge bases. The components' navigational features and drawing styles are versatile and can be applied to a variety of sidebar panels or special lists of items. They can also be used to extend the search functionality of any application.
Key features of the components include support for font size and color scaling, linear, logarithmic and custom scales, alignment and spacing settings, variable and fixed row heights, fixed column widths, horizontal or vertical tag placement, different styles for normal, hovered and selected tags, frames and background options, transparent background, ability to draw over the Aero Glass effect on parent controls, and mouse hover and click events for easy navigation.
Users can easily define tag items in design-time or run-time, and load and save tags through CSV files, TStrings and an array structure. Multi-page views and auto-sizing controls make for intuitive and user-friendly navigation. Additionally, the components offer fast binary searching of items, custom index labels support for TTagIndex component, complementary styler components, and full source code available on purchase or registration.
Overall, TTagCloud and TTagIndex components are powerful tools that can bring the valuable features of web navigation to desktop applications with ease.
