I have been working on a dashboard where a chart and a table are requested. However, both would contain the same data.
For instance, it is required that a country map is shown, with the values of each state color-coded. But it is also required that I show the same info in a table next to this map.
To me, this is clearly redundant. Visualizations were invented to understand tabular data faster and gain a better understanding.
The feedback I get is that "the client is table-person". This doesn't really hold its ground. "What if this particular person at the client leaves and someone who is chart-person takes his place?", ".... well then add an option to toggle between the chart & the table."
To me, this sounds like we're giving the user one more choice to make before he even starts to work with the dashboard. And not to speak of the additional (although trivial) programming involved.
How do you handle situations like this?
