In the windows world I would recommend Power BI [1]. Our nightly test server generates a lot of performance metrics which are stored in an excel file. We upload the excel to OneDrive and Power BI periodically refreshes a report dashboard which we display on a large screen within a browser. The designer (Power BI Desktop) is really nice. The data aggregation and shaping is powerful. The only drawback we experienced is that the provided visualizations [2] are sometimes a bit limited, there are custom ones [3] with varying quality though. You need Power BI Pro for this auto-sync scenario, but we got such a license for free through our msdn account.
