Feature request: SVG output for large visualizations

Summary

When generating visualizations with large inputs on chart operations such as: (Scatter, Heatmap, ...), the generated SVG output for the download file is escaped. It might be useful to have the ability to download the SVG as a file.

Although viewing the SVG can be achieved by changing the output threshold in the options, this may not be clear to the user.

Example

Sample python script generating 100k random data points

import random

with open('randomdata.txt', 'a') as data_file:
    line_count = 0
    while (line_count < 100000):
        data_file.write('{0}, {1}\n'.format(random.randint(1,100), random.randint(1,100)))
        count = count + 1
