 the actual Execution body. The property can be used to hide the Parameters section, making navigation easier.
 
+|`report.translations.<lang>.<translation key>`
+|Alternative translation for the specified key.
+|
+a|This family of properties allows overriding text values in report controls, such as labels, buttons, etc. These values
+represent translations for the chosen language. The list of languages and default translations can be found in the
+official report repository, for example, here is translation configuration for English:
+https://github.com/allure-framework/allure2/blob/main/allure-generator/src/main/javascript/translations/en.json[en.json].
+
+To override a translation value it is necessary to provide translation key, which is essentially a path to the value in
+JSON file. For example, to specify custom English message for duration chart without data the following property should
+be used:
+[source,properties]
+----
+report.translations.en.chart.duration.empty=No data to display
+----
