Sivaraman, have you added the repository to your pom?

<repository>
  <id>vaadin-addons</id>
  <url>http://maven.vaadin.com/vaadin-addons</url>
</repository>
Can you check that you actually downloaded vaadin-charts dependency into you local maven.
go to
homedirecory/.m2/repository/com/vaadin/vaadin-charts
and check that it has jar files there.
