Loading Data with HyperSpy

This example demonstrates how to load and visualize data using the HyperSpy library.

import hyperspy.api as hs
from em_database.data import BilayerWS2

# Load a dataset using HyperSpy
dataset = BilayerWS2()
data_path = dataset.download()  # Download the dataset if not already available
data = hs.load(data_path)
data
