Flux queries can be easily created using the Flux Builder in Chronograf, with similar syntax to InfluxQL, but with additional features such as automatic window sizing and aggregate functions like mean(). The new language is designed for working with time series data and allows for flexible querying of data from InfluxDB. The Flux query syntax is similar to InfluxQL, but with some key differences in how the `window()` function is used and the addition of aggregate functions.
