Heatmap Example

This workflow demonstrates different ways to use the Heatmap node. We use the Heatmap node from the KNIME Views (Labs). We have chosen to do a quantitative visual comparison using data about the Average flight delay (in minutes) on arrival time for domestic flights in the USA for QTR1 2008. You can find the entire dataset, in the workflow data area. Feel free to explore it. With the Heatmap node from KNIME Views (Labs), you can double-click and configure your chart, then click 'save and execute' and see the results without leaving the configuration window. We have created a component example in the workflow with widgets. You can visualize it in your Local Machine or execute it in the KNIME Business Hub. Definitely, it's a fancier and more updated visualization node. If you include it within KNIME components, you can build professional dashboards.
