Texts on the web need to be readable in order to be accessible to a wide audience. WCAG2.0 states that tests should not exceed the reading level of upper secondary education . Several readability measures have been proposed over the last centur y. However, these measures give an accumulated measure of the text and do not help pinpoint specific problems in the text. This paper pro- poses a text visualization approach that emphasizes readability issues in texts. The texts are visualized in the textual domain. Th e intention of the visualization approach is to draw the attention of the author towards the aspects of the text th at potentially are hard to read, allowing the auth or to revise the text and conse- quently making the text more readable.
