{"rows":[     {"key":["zeit.de"],"value":98},     {"key":["google.com"],"value":49},     {"key":["spiegel.de"],"value":20},     {"key":["spiegel.de"],"value":12},     {"key":["spiegel.de"],"value":20},     {"key":["spiegel.de"],"value":12},     {"key":["netmng.com"],"value":49},     {"key":["zeit.de"],"value":300} ]}
