Historical and live price data for custom charts

[bitcoinspot.nl]

Hi Y'all

For my dutch bitcoin-site bitcoinspot.nl i am currently using the bitcoincharts.com charts, but as you may well know they have a lot of outages.
So now i have found someone who is willing to program some custom charts for me>

So now i am searching for data that i can use for the live and historic charts. As far as i know you can use the mt-gox data but are there any other options available ?

Greetings from the netherlands
