2/10 🖼️ The Canvas:
ggplot(data = your_data) creates the canvas. Every ggplot plot begins here. You're specifying the dataset you're working with. But just this alone won’t visualize anything! #RStats #DataScience

3/10 🎨 Aesthetics (aes):
This is where you map variables to visual properties (like x and y axes). For instance, aes(x = variable1, y = variable2) would plot variable1 on the x-axis and variable2 on the y-axis. #RStats #DataScience

4/10 ✨ Geometries (geoms):
These are the visual elements. Examples include:
•geom_point() for scatter plots
•geom_line() for line graphs
•geom_bar() for bar charts
•Each geom function adds a layer to the plot. #RStats #DataScience

5/10 🌈 Scales:
Want to tweak color, size, or shape based on a variable? Scales can help! For example, scale_color_manual(values = c("red", "blue")) lets you set specific colors for your points or lines. #RStats #DataScience

6/10 🏷️ Labels & Titles:
Make your plot informative!
•labs(title = "Your Title", x = "X Axis Label", y = "Y Axis Label")
•This adds clarity to what your visual represents. #RStats #DataScience

7/10 🎨 Themes:
Clean up and style your plot with themes. theme_minimal() or theme_bw() are popular choices to give your plot a polished look. You can further customize every element with theme(). #RStats #DataScience

8/10 🔄 Faceting:
Want to split your plot based on a factor? Use facet_wrap(~factor_variable) or facet_grid(rows = vars(row_var), cols = vars(col_var)) to create a matrix of plots. Great for comparisons! #RStats #DataScience

9/10 🛠️ Putting it together:
An example plot:
ggplot(data = mtcars, aes(x = mpg, y = wt)) +
geom_point(aes(color = cyl)) +
labs(title = "MPG vs Weight by Cylinder Count") +
theme_minimal()
