Show HN: A hackable cryptocoin graph builder

It's definitely nice but feels too tightly coupled with the PHP+MySQL web stack, it's too big of a hurdle to install these two just for the purpose of storing some numbers and showing a simple HTML page with a javascript line graph.

Maybe consider:

- not storing the data in any database and instead fetching it through javascript when the page loads; sure it might take a couple of seconds to populate on first load but it's a small price to pay for the benefit of not requiring any database or server-side refetching cron jobs; most of the exchanges have publicly accessible APIs for fetching candles for every market.

- using a simple node.js express server to serve the (now practically static) HTML page

Be cautious about exposing this on the public internet-- it's vulnerable to SQL Injection through misuse of prepared statements as noted in https://github.com/derogab/coingraph/issues/1

Looks like "chart" would be more accurate, I thought/hoped "graph" was related to blockchain graph analysis which is quite interesting.
