BayesFusion has released Probability Distribution Visualizer, an interactive tool for visualizing expressions with probability distributions through Monte Carlo simulation.  When the distribution is transformed by an equation expression, the task is daunting even for an experienced decision analyst and requires considerable statistical insight.  The tool aids the process of choosing the right probability distribution over continuous data.  It is accessible to the decision modeling community through a web interface at https://prob.bayesfusion.com/.
