Iris Petal Length Predictor

Slide 1: Problem

Users want to estimate Petal Length without manual calculations or R knowledge.

---

Slide 2: Solution

• Input Sepal Length & Width into our Shiny app
• App predicts Petal Length using a linear model
• Visualizes prediction on a scatter plot

---

Slide 3: Demo (Embedded R Code)

# Train linear model on iris dataset
model <- lm(Petal.Length ~ Sepal.Length + Sepal.Width, data = iris)

# Example prediction
newdata <- data.frame(Sepal.Length = 5.1, Sepal.Width = 3.5)
predict(model, newdata)
