datanavigator

Interactive data visualization for signals, videos, and complex data objects.

datanavigator is a matplotlib-based toolkit for interactive data visualization that handles signals, videos, and complex data objects. It provides both simple tools for navigating data with minimal programming and a user-friendly API for building sophisticated data interaction applications. This versatility makes it both powerful and accessible, regardless of a user's programming expertise.

# Use the arrow keys to browse through frames.
# Press Ctrl+K to bring up a list of available keyboard shortcuts
# To extract a clip, 
#   1. navigate to the start frame and press 1
#   2. navigate to the end frame and press 2
#   3. press e to save the extracted clip
# run dnav.get_clip_folder() to find the saved video clip

# Or, you can extract a clip from the command line
clip_path = video_browser.extract_clip(start_frame=100, end_frame=200)
print(f"Extracted clip saved to: {clip_path}")

2. Browse time series data and mark events of interest
