Hi Anisha, That page simply lists ideas and wishes. No support exists currently inside Mapnik for drawing legends.
While legend generation is highly desirable, it is a non trivial feature to implement and will likely take significant developer time and someone stepping up to fund such work. Ideally legends could be output using Cairo (and potentially PNG with AGG) to allow for both bitmap and vector formats.
