## Your problem
You want to make a figure illustrating the distribution of GDP per capita for all countries within each continent using the `world` data in the `spData` package. Your desired figure looks something like the following:
```{r, echo=F, purl=F, warning=F}
library(spData)
library(ggplot2)
data(world)
ggplot(world,aes(x=gdpPercap, fill=continent))+
geom_density(alpha=0.5,color=F)+
labs(x="GDP Per Capita",y="Density")+
theme(legend.position = "bottom")
```
You have started working on the figure but can't seem to make it work like you want. Here is your current version of the code (and the resulting figure):
```{r, warning=F}
ggplot(world,aes(x=gdpPercap, y=continent, color=continent))+
geom_density(alpha=0.5,color=F)
```
You want to ask for help and so you know that you need to make a reproducible example. Starting with the code above, make the required edits so you can use `reprex()` to generate a nicely formatted example that you could email or post to a forum to ask for help. See the [reading](https://reprex.tidyverse.org/) for more help. Note: you do _not_ need to recreate the figure above, only to use `reprex()` to illustrate your question.
If you have extra time, try to fix the code above to make the first figure.
