// DataFrame demonstration in Ruchy
// This shows the new DataFrame literal syntax and operations

// Create a simple DataFrame
let sales = df![
    product => ["Apple", "Banana", "Orange", "Apple", "Banana"],
    quantity => [10, 20, 15, 5, 30],
    price => [1.5, 0.8, 2.0, 1.5, 0.8]
]

// Calculate total sales per product
let totals = sales
    .groupby(["product"])
    .agg([
        sum("quantity"),
        mean("price")
    ])

// Filter high-volume products
let high_volume = totals.filter(quantity > 20)

// Sort by total quantity
let sorted = high_volume.sort(["quantity"], descending: true)

// Select specific columns
let summary = sorted.select(["product", "quantity"])

// Create a more complex DataFrame with nested data
let customers = df![
    id => [1, 2, 3, 4],
    name => ["Alice", "Bob", "Charlie", "Diana"],
    purchases => [[100, 200], [150], [300, 400, 500], [250]],
    active => [true, true, false, true]
]

// Chain multiple operations
let analysis = customers
    .filter(active == true)
    .select(["name", "purchases"])
    .head(10)

// Join two DataFrames
let joined = sales
    .join(customers, on: ["id"], how: "inner")
    .select(["product", "name", "quantity"])

println("Sales Summary:")
println(summary)

println("\nActive Customers:")
println(analysis)

println("\nJoined Data:")
println(joined)
