When hovering over the legend (Google Visualization API), tooltip description appears hidden behind the report

1) Is tooltip over legend custom (from Google Visualisation)? I didn't find any information about such tooltips. This tooltip appears when legend is trimmed because is too long.

d3js: zooming to a display bigger than svg size

I have gone through a lot of examples, but just could not find what I am looking for. I have a chart which has 54 little bar charts in it. I want to implement following zooming features:
1) By default, the chart is displayed in a svg container of size 400x400. On clicking the background of the svg container, the whole chart redraws/pops out itself to a bigger display, say 800x800, but without disturbing the other elements in the html page.
2) Each little bar chart has a separate container for itself in the svg. On clicking the bar chart, just that chart expands/pops out in a bigger display while rest of the chart is still of the same size.
How can these two features be implemented ??
Thanks in advance !
I think what you're describing is a modal div (or dialog) on top of your current page. If so, you'll need two copies of your charts. One is the original (400x400) and the other is the modal popover (800x800). Since the popover is a completely separate SVG, it can be zoomed differently (showing all 54 little bar charts or one bar chart).
Popover
The popover should be clipped so, if you're zooming to show one bar chart, the others will not be visible. You can refine it so when one bar chart is clicked, the popover only draws one bar chart at a time.
The popover can be a simple div with a high z-order or a dialog. Here's a jQuery dialog. There are many.
Click handlers
You also need click handlers on each chart group the the main SVG group. Alternatively, you could have one click handler for all the bar charts and calculate when you are over the background or an individual bar chart.
g.on('click' , function(d){ ...do the zoom... });
