🎨 Hello, Beautiful Graphics!

package main

import "github.com/GrandpaEJ/advancegg"

func main() {
    // Create a high-resolution canvas
    dc := advancegg.NewContext(1200, 800)

    // Create a stunning gradient background
    gradient := advancegg.NewLinearGradient(0, 0, 0, 800)
    gradient.AddColorStop(0, advancegg.ColorFromHex("#667eea"))
    gradient.AddColorStop(1, advancegg.ColorFromHex("#764ba2"))
    dc.SetFillStyle(gradient)
    dc.DrawRectangle(0, 0, 1200, 800)
    dc.Fill()

    // Draw a glowing circle with shadow
    dc.SetRGBA(1, 1, 1, 0.1)
    dc.DrawCircle(600, 400, 120) // Shadow
    dc.Fill()

    dc.SetRGB(1, 0.3, 0.5) // Vibrant pink
