In Python data visualization, how do I expose a REST API?

In Python, you can expose a REST API using various frameworks, with Flask being one of the most popular choices. Flask is lightweight and easy to set up, making it ideal for creating RESTful services.

from flask import Flask, jsonify, request

app = Flask(__name__)

@app.route('/api/data', methods=['GET'])
def get_data():
    sample_data = {
        'id': 1,
        'name': 'Sample Item',
        'value': 'This is a sample value.'
    }
    return jsonify(sample_data)

@app.route('/api/data', methods=['POST'])
def create_data():
    data = request.get_json()
    return jsonify(data), 201

if __name__ == '__main__':
    app.run(debug=True)
