What is this tool?
Bar Chart Filter lets you upload CSV or TSV data to instantly create an interactive cross-filter dashboard of bar charts. Multiple bar charts are linked together — clicking a bar in one chart filters all other charts and the data table in real time. You can intuitively explore trends and compositions in your data, then share results via URL or export them as images.
