Oftentimes there are outliers in the data I want do visualize (e.g. all data between value 1 and 10 but few very large values like 100). This makes e.g. bar charts unreadable when binning because I have to decide between large bin size (hiding details in the parts of the data which are most interesting) or having the bars squeezed until they are not readable anymore. It'd be perfect to decide an lower/upper limit when binning and to summarize values below/above as "others".
