## Custom Colors Example

` + "```go" + `
customData := []piechart.PieSlice{
    {Value: 40, Color: "#FF6B6B", Label: "Red Section"},
    {Value: 30, Color: "#4ECDC4", Label: "Teal Section"},
    {Value: 20, Color: "#45B7D1", Label: "Blue Section"},
    {Value: 10, Color: "#96CEB4", Label: "Green Section"},
}
chart := piechart.Render(customData, "Custom Color Example")
` + "```" + `

## Simple Split Example

` + "```go" + `
simpleData := []piechart.PieSlice{
    {Value: 70, Color: "#FF9F43", Label: "Majority"},
    {Value: 30, Color: "#686DE0", Label: "Minority"},
}
chart := piechart.Render(simpleData, "Simple Split")
` + "```" + `

` + smallExample + `

## API Reference

` + "```go" + `
type PieSlice struct {
    Value float64 // Numeric value for the slice
    Color string  // Hex color code (e.g., "#ff6b6b")
    Label string  // Display label for the slice
}

// slices: Array of PieSlice structs containing the data
// title: Chart title (empty string for no title)
// Returns: SVG markup as a string
func Render(slices []PieSlice, title string) string
