What is this tool?
Voyager 2 is a visualization tool that supports Exploratory Data Analysis (EDA). It lets you load data in the browser and interactively explore and generate visualizations. The original project is a fork/derivative of Voyager developed on the Vega ecosystem, characterized by its combination of manual chart specification and automatic recommendations for exploration support.
Features
- Data exploration interface…Load data and interact through panels for field lists, chart encodings, filtering, and more.
- Visualization recommendation…Automatically generate related charts (related views) and multiple chart candidates using wildcards, displaying them alongside the current visualization (focus view).
- Partial specification with multiple chart generation…Use wildcards to simultaneously generate and compare multiple visualization specifications.
- Interactive operations…Drag and drop fields onto encoding channels and update visualizations in real time.
How to use
- Load data…Load tabular data such as CSV and review the field list.
- Specify the visualization…Drag fields to encoding channels (e.g., x-axis, y-axis, color) to create a visualization.
- Use exploration support…Simultaneously generate multiple views using wildcards, or use recommended views to broadly explore data.
- Adjust and compare results…Compare recommended visualizations and generated charts while deepening your analysis.
Data formats
- Tabular data (CSV, TSV)
- JSON
