I can tell facebook sentiment has turned and google just a bit.
These graphs are useful for what they are, but from a data viz perspective it could be better.
It's too hard to tell small movements in sentiment patterns occur over time because the bars are too close. The x-axis isn't labeled, I don't know from a glance how much time each bar encapsulates and not least the sentiment color axis is unlabeled.
To make it better, I'd want a line graph of sentiment over time, as well as a smoothed average. Any major events with a spike in sentiment could be labeled on the graph. Ideally the sentiment scores would be places in some context that is a good reference.
