## What it is
Lyra is an interactive, graphical Visualization Design Environment (VDE) that lets users create custom visualizations without writing code. Marks can be bound to data fields via drop zones and transformed through a visual data pipeline, with results publishable to the web.

## Use cases
- design custom charts without coding
- build visualizations comparable to hand-coded D3
- bind graphical marks to data fields interactively
- visually specify data transformations and layouts
- publish reusable web visualizations

## When to choose
- you want a no-code, drag-and-drop alternative to D3 or Tableau for custom visualization design
- you need more expressiveness than Tableau for bespoke chart designs

## When to avoid
- you need a fully-featured, actively developed tool - Lyra 2 is incomplete and development has stalled
- you only need standard chart types, where simpler charting libraries suffice

## Facets
- artifact type: application
- maturity: maintenance
- function: data-visualization, gui
- domain: data-visualization, web-development
- platform: -
- tags: visualization-design-environment, no-code, vega, drag-and-drop, web-server, nodejs
