Implement either two major and three minor, or one major and six

Major:

• Somehow make it clear when there is no selection, either sum button or label instead of charts with instruction to make a selection. (Rory) #110
• Resize histogram bin on zoom (or change x-axis to log {then this is a minor item}) (Vincent) #116

Minor:

• Sync airline colors across bar charts. (Lily) #109
• Remove "airline" axis label #96
• Pick up on side bar #108
• Change cyan city color on map to same color as line, either square or circle #97
• Remove "map" title #98
• Fix text width in sidebar #99
• Explore making map a bit bigger. Maybe zoom using .project(scale)? #107
• Logo for airlines #106
