Create several medium svg/jpg images with marker and road names to serve with Django

I would like to create several (200/day) map images of max size 400x400.

Those images will be served online -to anyone- using Django.

The desired contents and properties of each image include:

• Road names
• Zoom 17 or 18
• A marker at the center which represents the coordinates of interest.
• Max size 400x400
• svg format (jpg -at least- for smaller filesize compared to png)

A static map image seems not to be an option because the services that may provide it either:

• Are not free after a number of requests
• Do not provide svg or jpg formats
• Do not provide a marker

The most realistic idea might be to create the images on my server(s)(or home box somehow) with a call to a script, for the first time, and then serve the created file while keep runing a task of updating the older images.

Searching around for such a setup, I find that I have to use mapnik on a postgis installation.

Supposing that svg is the prefered format due to its quality of display on retina images:

• Is there a simpler or more capable solution for this task?

If not, I have scatterly read the following issues for svg images and mapnik:

• Mapnik may produce clunky svg files (on a cairo surface).
• An svg image may not include the road names.

Are the above difficult to resolve on a self-hosted setup?

Some help or a different approach is very much appreciated.
