8. The non-transitory computer-readable storage medium of claim 1 wherein the first visual property is a first size, and the second visual property is a second size that is different from the first size.

9. The non-transitory computer-readable storage medium of claim 8 wherein the first size is proportional to the first number of the first plurality of errors, and the second size is proportional to the second number of the second plurality of errors.

10. The non-transitory computer-readable storage medium of claim 1 further comprising instructions executable by the processor to group the first plurality of errors into a first group of errors of the first type and to group the second plurality of errors in a second group of errors of the second type.

11. The non-transitory computer-readable storage medium of claim 1 further comprising instructions executable by the processor to receive, from an input device, a user selection of the application from which to collect the error data and for which to generate the visualization data.

12. The non-transitory computer-readable storage medium of claim 1 wherein the first linkage has a third visual property based on at least one of the first number and the second number.

13. The non-transitory computer-readable storage medium of claim 12 wherein the third visual property is a third size.

14. The non-transitory computer-readable storage medium of claim 12 wherein the third visual property is based on the first number and the second number.

15. A system comprising:

a processor; and

a memory comprising instructions executable by the processor to:

collect error data representing errors occurring in a plurality of instances of a sequence of operation caused by execution of code of an application;

group the errors into a first group of errors of a first type and a second group of errors of a second type other than the first type; and

generate visualization data representing an error flow diagram to display on an output device, the error flow diagram comprises a first block, a second block, and a first linkage between the first block and the second block, wherein the first linkage has a first visual property based on at least one of a first number of the first group of errors and a second number of the second group of errors.

16. The system of claim 15 wherein

the error data further represents a third plurality of errors of a third type occurring in the plurality of instances of the application, and

the error flow diagram comprises a third block and a second linkage between the first block and the third block, wherein the second linkage has a second visual property based on at least one of the first number of the first group of errors and a third number of a third group of errors.

17. The system of claim 16 wherein the first visual property is a first size and the second visual property is a second size, wherein the first visual property is based on the first number and the second number, wherein the second visual property is based on the first number and the third number.

18. The system of claim 15 , wherein the visualization data represents that, for each instance of the plurality of instances, an error of the first group of errors occurring in the instance occurs later than an error of the second group of errors occurring in the instance and later than an error of a third group of errors occurring in the instance.

19. A method comprising:

collecting, by a processor, error data representing a first plurality of errors of a first type and a second plurality of errors of a second type other than the first type, wherein the first plurality of errors of the first type occur in a plurality of instances of a sequence of operations occurring due to execution of code of an application, and the second plurality of errors of the second type occur due to the plurality of instances of the sequence of operations; and

displaying, on an output device, a visualization comprising an error flow diagram linking a first block having a first visual property based on a first number of the first plurality of errors and a second block having a second visual property based on a second number of the second plurality of errors, wherein the visualization represents an inference that the first plurality of errors caused the second plurality of errors.

20. The method of claim 19 wherein the visualization represents that, for each instance of the plurality of instances, an error of the first plurality of errors occurring in the instance occurs earlier in time relative to an error of the second plurality of errors occurring in the instance.
