Looks great! You might want to also try out an example using scattermapbox in plotly. Here are the docs: https://plot.ly/python/scattermapbox/

Scattermapbox looks great! Thanks for the fyi.

THANK YOU for this excellent introduction.
Trying to recreate your examples; can you point us to "california.jpg"? Likewise for any other media assets in your demos. Maybe put a link directly in the notebook. Thanks...

Hi there!

I was trying to use a png map of HK to pinpoint the values of airbnb apartment, but I can only get the map (HK map), not the points! Any idea why? Providing the code and the data here, thanks!

import numpy as np
import matplotlib.image as mpimg
hk_img=mpimg.imread('C:\\Users\\Filippo Sebastio\\Desktop\\hk.png')
ax = df.plot(kind="scatter", x="longitude", y="latitude", figsize=(10,7),
                       s=df.accommodates*10, label="population",
                       c=df.price, cmap=plt.get_cmap("jet"),
                       colorbar=False, vmin=0, vmax=10000,
                      )
plt.imshow(hk_img, extent=[-113.94, -114.32, 22.22, 22.37], alpha=0.2)
plt.ylabel("Latitude", fontsize=14)
plt.xlabel("Longitude", fontsize=14)

prices = df.price
tick_values = np.linspace(prices.min(), prices.max(), 11)
cbar = plt.colorbar()
cbar.ax.set_yticklabels(["$%dk"%(round(v/100)) for v in tick_values], fontsize=14)
cbar.set_label('Price', fontsize=16)

plt.legend(fontsize=16)

the data

Regarding the missing california.png file, I just dowloaded a png map of California and save it next to my notebook.

I found the california.png image being used here https://en.wikipedia.org/wiki/List_of_counties_in_California#/media/File:California_Locator_Map.PNG

Hello!
First of all, thank you @iandow for sharing this exercise! Got really excited after finishing it.
Used the Matplot Lib, it's the one i'm most commonly used to. Also thanks to @robianmcd for sharing the California.png
Really helped me learning a bit more :)
