asyncio.run(example())
  1. AsyncIO is Python's built-in library for writing concurrent code with the async/await syntax.
  2. This is optional and is imported in this example to show how to visualize the result using Plotly.

}
  1. This type determines the style of the trace
  2. The legend name
  3. The component names

Note

The ternary plot direction cannot be changed in Plotly and differs from the SciGlass convention. See the Python example code for details on how to parse the data points.

Note

Data points are stored in the value key,separated by a special delimiter \x7f.

The first value means the value of vertex at right (C).

The second value means the value of vertex at top (A).

The value of (100 - A - C) means the value of vertex at left (B).
