Time Series Visualization Does anyone know how I could create a graph like this one to visualize time series of anual temperature for different years in R?

Thank you very much for your help! :)

This is a standard surface plot. Just look for "plot a surface over the an x-y plane".
Such plots can be created with base R but they are many other packages (e.g. rgl, ggplot, etc.) that offer similar (and more sophisticated) functionality. Here is a quick proof-of-concept with base-R:
set.seed(14)
x <- seq(1772, 2017, by = 10)
y <- seq(-2, 5, length = length(x))
z <- outer(x, y, function(a, b) sin(b)) + runif(n=length(x)^2, max=0.3)
persp(x, y, z, phi=10, theta=-50)
